In fact, many of the other companies in the space are looking down their nose at Tesla's experiment because Musk thinks he can do the trick without LIDAR. He might not be wrong (humans do it without LIDAR), but it's a hell of a gamble that results in a sensor bundle quite different from the sensory tapestry other self-driving vehicles can take advantage of.
Couple that with the fact that other companies are employing professional drivers to test their hardware on public roads while Musk is crowdsourcing it to anyone rich enough to buy one of his cars, and one can get the sense why those who are actually concerned about driver and pedestrian safety are real nervous about Musk's foray into this space.
Or those Jurassic park like vehicles
