This projects onto the road ahead of the bike, hopefully making your presence known even if you weren't visible (blind spot, for example).

If it only shows up on the ground, near the side of the front of the car, this won't work. I'll never see it.

If this is more like a visible beam, that is also very visible before it hits the tarmac (which I doubt), then it's essentially a torch. We have those.
