Yeah, saw a (completely unrelated to Tesla) talking about LIDAR on vehicles and saying how much of a failure it was. Radar and USS likewise have several limitations, I never trusted multimillion dollar with peak output power in the Mega Watts (stuff that would fry a person if they were standing in front of it) for the kinds of detail that radar systems in cars, operating in the milliwatts try to achieve. That's why they are so susceptible to reflections, side-lobes etc."Elon's an idiot. We need LIDAR. it can't work on just vision!"
"It won't work with out RADAR!"
"It can't park without USS!"
The new auto-park is looking fantastic.
There'll always be the armchair experts sprouting off about how dumb Elon is and by inference how much smarter they are, but I'll never bet against the guy who has revolutionised the auto industry, made EV's viable and turned space flight on it's head at the same time (along with a dozen other 'smaller' things).
