Me wild and crazy college buddy and spy tried this on a test drive of a used Chevette.
The poor little white car had a crack across the entire window, but somehow offered for sale.
We did it on South State street in SLC and the tires screeched loudly as they spun backwards while the car hardly slowed in reverse. This was a bit surprising, but we as Physics students at the time understood why.
My other friend used to joke that āPā was for Pass, but we never tested that.
