Flying-Leap Crash Avoidance

This car has 4 emergency 1-shot pogo sticks built into its structure, near the wheels (since in general car wheels are located specifically to balance the load). At the bottom of each stick is a spherical roller, much like the ball-point at the end of the average pen. It does not normally touch the ground when the car is in normal motion.

The top portion of each pogo stick contains a permanently sealed and compressed fuel-air mix. When ignited by a spark plug, it powerfully propels the shaft downward, breaking the seal that had held the piston in the maximum-compression position. There is nothing to prevent the piston from completely leaving the cylinder of this pogo stick, after firing -- which is why it is a 1-shot device.

The car has a number of sensors built into it, and an Artificial Intelligence specially trained to recognize serious collision situations. If it computes that there is nothing the driver of the car can do to avoid a collision (it might be the fault of the driver of an oncoming truck), it simultaneously activates the 4 pogo sticks.

The car now takes an emergency flying leap, avoiding getting hit. The CAR might do some hitting when it comes down again, but here the cushiony car-seats significantly help the passengers, and of course the A.I. could inflate all airbags during the flying leap, as additional protection. A parachute might be deployed, too (perhaps using small rockets for max deployment speed).

If the Flying-Leap Crash Avoidance system successfully protects the car, then new pogo sticks can be installed, an so on. There shouldn't be any need to replace the whole car.
