it gets really close. and it has quite a jolt, obviously, but we haven't hit the child. whereas the tesla... that was quite something. this technology has already been built into cars right now as a safety function, and in the future could be used in autonomous vehicles too. this tesla and other cars with current collision avoidance systems have their limits as to what they can prevent. accidents still happen, but lidar has the potential to raise the bar — even in low light. there's a general assumption right now that automatic emergency braking or collision avoidance systems are a solved problem on cars. but the reality is the opposite, people still get into car accidents all the time, and this is despite now the substantial majority of new vehicles being produced with assisted driving capabilities. the reality is, you would think it would be easy to build system that willjust prevent you from hitting the thing right in front of you, but that's simply not the case with these existing
