The use cases I know of for lidar don't usually include a glancing reflection off a large flat surface.

  Colliding with a large angled piece of sheet material in the middle of a roadway doesn't sound pleasant.

    While I agree that the sensor systems should image just about anything you can imagine, wouldn't a large angled reflective sheet produce a shadow that could be distinguished from normal road surfaces and avoided?

      That's a good 1st cut. But if we review the prior art -- namely stage magic's tricks with mirrors -- what's to stop someone from putting something in the region of the reflected image that would be expected by the driving AI? So, if what's expected are bushes in the background, why not aim the mirror at other bushes at the right distance?
