No, it’s just a bad take. Every other manufacturer of self driving vehicles (even partial self driving, like automatic braking) uses LiDAR because it solves a whole host of problems like this. Only Tesla doesn’t, because Elon thinks he’s a big brain genius. There have been plenty of real world accidents with less cartoonish circumstances involving Teslas that also would have been avoided if they just had LiDAR sensors. Mark just chose an especially flashy way to illustrate the problem. Sometimes flashy is the best way to get a point across.
The consequences are people standing up and doing something. Even non-violent resistance can make it effectively impossible for ICE to detain someone.
If no one is willing to do that, then no, there are no consequences.
