The simple reason why they don’t do it: It has to be 100% reliable. Robots get stuck, need charge, software has bugs, … So your fleet of robots would need supervision. Probably for years to come.
And a human driver only costs like 70-80k a year.
The point of machine learning based systems (imo) is that they aren't 100% reliable.
Idk where people are getting the idea that systems designed to mimic biological brains will have machinelike precision whilst also being flexible to adapt to new situations.
Yeah, but this requires good teleoperator infrastructure. You can’t unstuck a robot that loses connection. There are just a lot of things that can go wrong. And an entire car being stuck and waiting for someone to come is also not cheap.
I am pretty sure Amazon (one of the biggest robotics company on the planet btw) has done the math.
