The formula for angular acceleration is A=v^2/r. Solving it
for r (the turn radius) gives r = v^2/A. For 45 mph in a
turn to cause 1.1g angular acceleration, the turn radius is
123 ft. Looked at another way, if you want to limit cars
that can do 1.1g to 45 mph in turns, the maximum turn
_diameter_ you can set up is 446 ft.
