The laser light that could cut cyclist deaths
- ljf 13y agoThere was a previous discussion of this, I'll see if I can find it. Main issues were that laser was of an illegal wattage, and the drivers look in their rear view mirrors for lights at mirror level, not on the floor/road. Looks good but in the real world has limited use. If the road has bright streetlights then the laser is nearly invisible on the ground, and if the driver can see the laser beam directly, well that is a serious danger.
