Why can an electric car, not have a generator instead of a motor on one wheel, so that as that wheel turns it generates energy for the battery? I totally understand that it isn’t possible, but I don’t know why. I also understand that regenerative energy is taken from breaking.

assume the car is set up so the front wheels are connected to the motor pulling the car forward, and the back wheels are connected to the generator, Then to get all of the energy back with the generator, the back wheels would need to pull the car backwards with the same amount of force that the front wheels will be pulling the car forward. The result will be that the car goes nowhere.
And if electricity is sent to the motor without it moving, all of the electrical energy going to the motor would be converted to waste heat.
