I've been suspicious of the practical reality of self-driving vehicles since I first heard of them, so this is no surprise to me. I had not heard of teleop actually being used in trucking at the current time. A quick Google gave me so much noise about its use in other fields that I don't have time to start digging deeper at the moment.
Only surprise here is that it took investors so long to clue in. Also that the founder still thinks teleop makes any sense. There's never been a doubt in my mind that L3 is the threshold for human equivalence. And even at that point I've never seen any real explanation on how liability will work when we have autonomous cars killing humans. I don't care how much better they could ever theoretically get, it would still be a large non-zero number and the psychological effects are different.
This was oddly moving.
