Yeah, the "lidar is useless" guy whose cars are consistently crashing into things when visibility is bad is telling us that he can do the same thing with missile targeting systems... Sounds like a great idea
And F-35s are really fast. By the time you recognize and can target it, it'll fly behind a cloud or something. So not only do you need to make a really fast rocket w/ vision-based AI integrated, it also needs to be able to detect said plane at great distances, as well as maneuver well enough to see it as it exits clouds and whatnot. That's a lot more complicated than slapping radar on something with heat tracking at close distances.
He's not, otherwise he would know that "low light sensitivity" cameras aren't "sensitive in low-light conditions" but "with lower than normal light sensitivity".
In an imaginary world where cameras are way more expensive, he'd absolutely be pushing LiDAR in cars. The metrics he cares about are cost and marketability (cool factor), or money for short.
