Elon Musk's "fully autonomous" cars will, like other robotaxi vehicles, rely on remote human pilots.
Silicon Valley wants us to believe that their autonomous products are a kind of self-guided magic, but the technology is clearly not there yet. A quick peak behind the curtain has consistently revealed a product base that, at a minimum, is still deeply reliant on human workforces.
It's been 7 hours of driving random people around the city, name after name I'll forget quick, then I see a name that brings my blood to a boil, an old bully/tormentor, I take over the car and deliver the script perfectly, he doesn't remember my voice, why would he? We head off and he zones out staring at his phone, completely oblivious to the fact he is heading towards his doom, we come to a train line and my internet connection 'drops', causing the vehicle to come to a complete stop, a minute later a large train smashes into a the car, completely destroying it and killing them before I can successfully reconnect to them.
Once again, they don't remotely (pun intended) have that capability, and how do you plan on them not tracking it back to you? Much easier to use one of the possible 500m guns in America.
Your idea gets a high dollar investigation into how it happened. With the company at risk for millions/billions in losses looking for the culprit. It's all nonsense.
