I found a Model S I'm interested at a Toyota Dealership from another state. This will be my first Tesla. How can you tell without actually driving the car if Autopilot is in fact activated? It seems like the car does, in fact, have the hardware when I asked them to check the front wheels and there were sensors at the very front part of the front wheels. Of course, I'm going to be getting photos soon to double check. So anyways...can you tell through the dashboard monitor if it indeed is literally activated? Thanks!
