O yeah,they even let us know if someone is on our blind spot on the right side even if we don’t se them and the Volvo’s even honk the horn on the truck.
i saw a documentary of self driving trucks a couple years ago. i think it was done in death valley? short story is the trucks would do as you stated and still needed a driver as a backup! think of those giant farm tractors that plant or harvest according to the gps programming you write to their eeprom or maybe hard drive.
