It takes energy to make that motion. Wheels turning that also spin an alternator are taxed with the load of the alternator having to charge the batteries (they don't free wheel). The harder it is to turn the alternator the more energy is drained from the batteries to turn the wheels to maintain the same speed.
Perpetual motion is the theory that a machine can produce it's own energy and enough of it to maintain itself w/o any additional resources.
It's a pipe dream much like turning lead into gold.
If cars had solar panels on the top and out of sight they could produce some charge especially with short commutes and if your car sat out in an open sunny parking lot all day. You couldn't drive endlessly into the sunset but they would produce a little power. Perhaps enough to get you home.
