why haven't we seen cars with hydraulic powered front wheels that can turn 90 degrees to the vehicle? Normal power would come from the rear wheels and the fronts would just free roll while not in use but when you want to turn on a dime the fronts would turn 90 degrees and be powered by hydraulics. Works for forklifts.
FWDs just ass in, handbrake and spin the wheel till they fit.
My FWD handbrake was good enough to hold the car on a hill but not quite strong enough to enable you to do this trick. The tyres had too much grip & just overpowered the handbrake.
