...the driver. HOW DOES A CAR DO THAT Can you explain to me how that works?

In order to do a parallel park, you would have to position the LS next to a parked car. Then, put the LS in reverse and turn on the Park Guidance System. Set it to parallel park (the LS also can do a 90 degree park) and let go of the wheel. The LS uses a series of sensors that measure the distance between you and the parked car, and how far away you are from the parking stall. The sensors then send that information to a computer that will calculate that information and will control the steering wheel. The only driver input required is the use of the brake pedal to control the speed and stop the car. In my personal opinion, this is a safer way to park because human error is greater than computer error.

laser sensors

you put the car in auto park and then it parks itself! the only thing you can control is the brakes which is stupid! the car is nice but th e idea is dumb as hell! its a waste of money as well! if you planning to buy it don't bcuz you would end up looking for something worth your money! "-" telling the honest truth!!!!!! ^~^
