A system of brakes for cars which during strong brakes deflates the tires.
Slightly deflated tires have stronger grip on the ground (while consuming the rubber more). Would it then be a good idea to incorporate, as a security device in cars, besides airbags and the rest, also an electronically triggered valve, letting air escape during strong brakes?
I have no idea if this could realistically work.
One could also have a pump which would slowly bring the tire pressure back to normal after a false alarm.
