I've seen this before. Interesting idea. I would imagine they have to have mirrors spinning inside to generate the ground pattern. I wonder what the durability of that is and how long a charge will last.

Yeah, this has come up before and been a subject of much debate. Not something I would use myself, but if it works for you then go for it!

Oh, and btw, when these come out, I am going to buy like 23 of them and strap them all over my bike.
And film it and post said film on youtube with a Norwegian black metal soundtrack?

Spinning mirrors? Looked like a fancy laser pointer to me.

Laser pointer makes a dot. To make shapes, the light has to be diffused or moving. Diffusion would potentially make the light dim, so I went with the spinning mirror theory.

I am going to guess based on the tiny case size and the fact they are going with a green laser that they went with diffractive optics instead of spinning mirrors. :D Also, it would seem more cost effective and reliable to eliminate moving parts.

Looking at the video, I just can't think of a time when that would be helpful for me. If my entire ride was always on wide streets it would make sense, but it doesn't make sense when I'm taking the lane. It seems like then it would promote illegal passing (must change lanes)

Can't cross double yellow to pass a bike where you ride?

Is it not legal where you ride? In Ohio, it is permissible to overtake even in a marked no-passing zone when a slower vehicle is moving at less than half of the posted speed limit.

From the Ohio Dept of Transportation website:
4511.31 Hazardous Zones - Allows for the crossing of a double yellow line in instances when drivers are approaching a slower vehicle (bicycles, horse-drawn buggies, farm vehicles, etc.) proceeding at less than half of the posted speed, as long as the faster vehicle is capable of passing without exceeding the speed limit and as long as there is sufficient clear space in which to do so.​

The official law on the books is a bit less direct and readable:

4511.31 Establishing hazardous zones.

(A) The department of transportation may determine those portions of any state highway where overtaking and passing other traffic or driving to the left of the center or center line of the roadway would be especially hazardous and may, by appropriate signs or markings on the highway, indicate the beginning and end of such zones. When such signs or markings are in place and clearly visible, every operator of a vehicle or trackless trolley shall obey the directions of the signs or markings, notwithstanding the distances set out in section 4511.30 of the Revised Code.

(B) Division (A) of this section does not apply when all of the following apply:

(1) The slower vehicle is proceeding at less than half the speed of the speed limit applicable to that location.

(2) The faster vehicle is capable of overtaking and passing the slower vehicle without exceeding the speed limit.

(3) There is sufficient clear sight distance to the left of the center or center line of the roadway to meet the overtaking and passing provisions of section 4511.29 of the Revised Code, considering the speed of the slower vehicle.

(C) Except as otherwise provided in this division, whoever violates this section is guilty of a minor misdemeanor. If, within one year of the offense, the offender previously has been convicted of or pleaded guilty to one predicate motor vehicle or traffic offense, whoever violates this section is guilty of a misdemeanor of the fourth degree. If, within one year of the offense, the offender previously has been convicted of two or more predicate motor vehicle or traffic offenses, whoever violates this section is guilty of a misdemeanor of the third degree.

Effective Date: 01-01-2004; 09-21-2006

It's COOL, is it practical and going to replace a good bike light and reflective clothing, I sure hope not. Personally I would hate to see it on the trails I ride.

really??
a red light shining a false bike lane???

am I the only one thinking "most drivers don't stay out of the REAL bike lane nevermind one that moves with me?"
since when is pointing light at the ground make people more aware of you than pointing light at their eye height?

*sigh*
probably all been covered before, sorry, incredulity strikes again...

I think that's the general consensus. People around here drive in the bike lane all of the time (despite the fact that it earns you a big, fat ticket) and I'm sure it's that way elsewhere as well.

seems pretty useless
dont see how a little line on the road could possibly be anywhere near as effective as some bright flashing red led lights on the cyclist or bike

EDIT: I guess I missed the point - despite the photos and videos showing cyclists without any other lighting the text suggests it is intended to be used in conjunction with other lighting since lights are effective at capturing motorists attention and this is intended to show them a boundary around the cyclist. Still pretty useless IMHO.
