I've got an invention I call "MyHouse". It's a big projector that shines an image of my living room on the walls. You can bring it into a store or a bank, set it up and then basically just pocket whatever you want. "It's MyHouse!"

Dining Room Edition available soon.

This seems kind of brilliant, pun intended. I don't bike at night much, but if I did, I'd consider this. I hope it's easy to remove and take with you, though, because it's probably theft-bait.

Wonder if it's legal.

Why bother following posted traffic signs when you can just create your own?

Is this not quite literally the most dangerous "road safety" idea anyone has ever come up with? The cyclist gets lulled into thinking they're somehow protected by their arbitrary decision to declare that wherever they happen to be riding is a bike path, while the baffled motorist either ignores it (endangering the cyclist) or obeys it (endangering him or herself if they must drift further out into the center of the road).

It's pretty neat but I don't see how it's legal. What's to stop me from having one that makes a crosswalk wherever I go?

As a way to alert cars, it's great, but it seems too much like it's trying to make some sort of statement.
posted by bondcliff at 11:46 AM on June 24, 2009


It does seems like this would become a big problem whenever the cyclist needs to move into traffic, e.g., to make a left turn. Would be a lot better, and more expensive, with an easy on-off control.

It's like a little finish line cars will need to cross before they can hit you when you run a red light.

I agree Game Warden- this seems like it could turn into a huge biking FAIL. From my experience in NYC, I think the safest thing bikers can do is actually follow the traffic laws. Helmets, reflective gear and lights for night-time riding are obviously a great idea, but actually creating your own traffic signs seems problematic.

Has anyone seriously suggested that these glowing green lines would be mistaken for a bike lane? If so, they are idiots. With that out of the way, the point is clearly a boundary of personal space, a projected line saying "I prefer that you not come any closer than this when passing me". This is reasonable, if a bit of a novelty, since any reasonable motorist should be giving a bike a little more space than I saw in the video anyway.

The video would be more compelling as a safety idea if the rider didn't make a left turn through a red light at one point. Otherwise, a neat idea if not the best idea.

I can't find the site, but there's one product which is essentially underbody lighting for you bike on the downtube or rear chainstay and man, that thing is BRIGHT. Putting yourself in the middle of a really bright circle of light that's not blinding drivers at the same time is a much better idea.

I think it's safe to assume that if you're safety conscious enough to use this then you're not swerving into traffic convinced that you're protected by LASER POWER. And if you are thinking that, then you'll be making idiot decisions on a bike with or without this device.

Giving drivers a visual cue seems like a fantastic idea. I live in a pretty damn bike-friendly town -- Portland, Ore. -- and I still want one.

This seems like those flashing headlamps some motorcyclists use...they do realize I, like Homer Simpson before me, suffer a moth-like compulsion towards blinking lights....

It's not about whether anyone would seriously mistake this for a bike lane when they stopped to think rationally about it. It's to do with the hundreds of cues you rely on from your environment when doing something as complex-yet-second-nature as driving a car. People could easily react to these things as if they were bike lanes, it seems to me — with really, really bad consequences — without necessarily believing that they were bike lanes.

I see it as more of a: "You should be at least this far away from me when you pass."

The problem is, safe passing distance is a pretty complicated combination of bike speed, car speed, and road conditions.

Complicated to express, that is. Most people do a pretty good job of figuring it out on the fly. The people who fail are generally letting their emotional state take over from their common sense. Like "god damned bike in my way, I'm going to buzz him." Or "poor cyclist, so dangerous for you, I'll use the oncoming traffic lane because it will be safer."

It just doesn't seem to work very well.

it's akin to an incadescent light powered by a couple of AAs in terms of intensity. It would be OK in pitch black but in a lit urban setting it doesn't do much. Besides, drivers never look at the spot where it puts the light. $25 at REI gets you 10x as much light on your seat post and for $100+ you can probably get 100x as much light in a headlight which you need anyway.

It looks neat though.

You know, its like this: You should only get so close when passing a bike There is a line that you never ever pass. This device is about where that line should be, if not closer.

Always always wait until you can pass safely, never squeeze by.

So, if this device would change how you passed a bicyclist, you are currently passing them in an incorrect and unsafe fashion.

I'm pro-cyclist. I bike and I also drive a car. I still think this thing is a bad idea. I just see it as a big, bright, distracting light that would draw a driver's attention to the pavement, wondering what the hell that green blinky thing is, while they drive closer and closer and fail to see the cyclist it's supposed to be protecting.

Blinking lights on the bike and a safety vest draw the driver's eye towards the bike, where the eyes should be drawn. This thing would also give the cyclist a false sense of security, I think.

The only time I see cyclist hate here is when Critical Mass gets mentioned. Most of the comments so far have been pretty well-reasoned, unless I skimmed past the hatey parts. For myself, I spent five years with a bike as my primary mode of transport. So when I say that this is a cute idea but not really practical, and possibly even dangerous to the cyclist, it's not out of unreasoned cycle-rage, it's from personal experience.

I'm sure glad that I live in a city that is cyclist friendly.

I wish we could all say that.

This is an amazing idea.

I think the producers of this should get away from the "bike lane" idea and describe it as a boundary like Decimask said. This device helps defines a space around you that you would like respected.

For those who think that it's a dangerous idea - do you really believe that the rider will really think they have made a real bike lane for themselves? No - the biker can continue riding defensively and this device can offer an additional measure of protection or at least visibility.

My only concern is that its novelty would have the opposite effect of warding away vehicles. I wonder if car drivers would be unconsciously drawn towards the lines - much like drunk drivers are drawn towards the lines in the middle of roads.

There are, in fact, laws about what lights you can affix to a vehicle. In Missouri, for example, if you have a blue light on your vehicle (no matter whether it's on top, on the license plate, or undercarriage) and you're not an emergency vehicle, you're getting a ticket. Have no idea whether there are rules about lights on bikes. (Missouri is vaguely aware that bikes exist, kinda sorta).

Well, that's not entirely true as stated at the Missouri Bike Federation: Missouri Statutes for Bicyclists.

Missouri is aware there are bicycles mostly, but the drivers try to kill you anyway.

That being said. The DIY Ground Effects for the bike seem more effective than the bike lane anyway.

Anything that makes bikes a bit more visible is a good thing. The bike-lane graphic is obviously contentious and seen as arbitrary, so why not a simple box?

Anyway, this is why I mounted a 2500 watt CO2 laser on my bike. The shower of sparks it makes when it slices an running engine block in half is highly visible.

I always thought it'd be cool to have a laser-generated grid projected in front of the bike (on the ground) to provide the rider with an indication of the topography and other surface properties of the road at night-- sometimes it's hard to tell if a shadow is a pothole or an oil slick.

If it could project animating stars or skulls onto the ground, it would increase both visibility and pimp factor.

This could probably be done on the cheap with a few of those cheap laser pointer toys that include various diffraction gratings that have graphics like a soccer ball, middle finger or such. It can't be that hard to etch your own diffraction gratings for projections considering you could probably do home holography with a sandbox and a 10+MW laser that cost less than 50-100 bucks for a high powered diode module.

I have no idea how much a "galvo scanner" costs these days but I hope it's cheaper than it used to be. Basically you need two computer controlled mirrors to give you X-Y scan control of the beam and a laser of sufficient brightness to bounce through it. There has to be a cheap way to rig one with scrap and a Basic Stamp or something. Used hard drive servos? Maybe a clever one-mirror solution?

If someone solves this scanner or diffraction grating problem cheaply you could even do laser diode "throwies" that broadcast a tag or image. Make 'em solar powered and light-aware so the broadcast at night. Put a mic on them so they shut off if humans-approaching sounds happen so it's harder to find them.

In one of our future timelines graffiti artists have hand-held laser etchers and cutters.

In regards to blinding or distracting motorists, did anyone watch the video? It's a pretty paltry steady light, especially when compared to the photos of the glowing bike frames. It's aimed at the ground, behind the bicyclist, where bicyclists usually aren't looking (except for those with little rear view mirrors). No flashing or blinking lights, and it's not even that functional under decent street lights (at least as seen in the video). The still photos don't seem to be representative of the real-world appearance.

I dig that extensible taillight. That seems like a pretty neat solution, as long as it could be folded back against the bike when it wasn't needed. For that matter, put one on each side, so the pair of taillights resembles a larger motor vehicle. That's the visual cue most drivers are trained to recognize, not to mention giving the drivers behind you the advantage of some depth perception enhancement.

I had hoped that a bonus effect of wire baskets would be to encourage drivers who valued their finish to keep their distance, but the last couple of weeks have shown me that some idiots just don't care.

So I'll have to move on to Plan B, which involves a full grown raccoon and some duct tape, but I'll be damned if I can find that roll of tape.

Well, going by that article, what you need is a helmet with a wig on it. The wig gave even more space than no helmet did, and if you got into an accident you'd still be protected. But this way drivers will simply think you're a large-headed woman.

It is when the bike is upright. What happens when the cyclist takes a turn at a very sharp angle or even has a minor fall and suddenly the angle of the laser is shooting into the eyeline of pedestrians or cars? Way to blind somebody. Seriously, all lasers are dangerous when aimed directly into human eyes and this seems like a horrifically unsafe way to mount a laser. At the very least it requires an orientation sensor that turns it off when the frame of the bike goes more than say 20 degrees from vertical.

Oh, and when I see a car coming up on me and have a feeling they're going to try to squeeze by me, I do this:

1. I weave a bit, drunkenly, and take up a bit more space. I try to look unpredictable.
2. I move over to the right (where I started) just as the car's about to pass me.

It's sort of exploiting that brief reaction that every driver (including myself) has when they think someone's going to do something unpredictable: oh shit, they're going to hit me. That, plus I have room to wider the distance between myself and them.

Oddly, when I started riding a motorcycle, I quickly found it feels a lot safer, because you take up a whole lane and can go their speed, so nobody gets angry (well, almost nobody) and nobody tries to squeeze you (well, almost nobody.) Based on my experience as a cyclist, the first time I rode my motorcycle I assumed cars would rush up on me and try to knock me over, but they are much more respectful (although still not nearly enough.)

Trying to do it in moving traffic would be somewhat more dangerous, but I can't think of many circumstances when that would even be possible for a cyclist--well, possible, but obviously extremely stupid.

The only dangerous parts are the possibility of a car darting after an empty spot ahead, or cars leaving gaps for left turning oncoming traffic. In fact, I find it easier to spot the left turning traffic while lane splitting, because I'm one lane closer to the action, and I'm moving slower anyway. Using bike lanes on streets with congested car traffic, where I could go 30+km/h, avoiding the left turning cars means I have to slow down anyway--and you think lane splitters are irritating!

Motorcycles lane splitting on highways, so that they can move at 30-50km/h where other traffic is moving under at say 20-40km/h, seems like it would be more dangerous. Not something in my direct experience though, so it is just wild speculation.

Actually, thinking about it.. When avoiding an unoccupied right turn lane on a larger road (because idiots would otherwise pass my ~30km/h at 60km/h and end up turning right directly in front of me), there is an entirely different circumstance that could be interpreted as lane splitting.
