Why don’t we have systems like this in place for automobiles?

Mostly the size of the batteries needed. There have been proposals but you need something like a quick lube change location so you could drive in, have a hatch on the vehicle opened, a large several hundred kg battery pulled out by a robot arm and a fresh one installed before driving away, probably (knowing American capitalism) for an “appropriate” service charge. So - a vehicle built to accept a standard battery, a standard battery, a standard changing station and a standard charger at the station. All built new.
