Now that you have me thinking, why not electromagnetic shock absorbers
for cars? They could be controlled by a microprocessor. Phase
cancellation for bumps..

It'd take some big motors, but could be done. Probably has
been, somewhere somewhen.

People (well, actually, electrical and mechanical engineers) have been
working on this for quite a while. As you noted, it takes a lot of power and
expensive hardware. Closest you can get to it right now is
electromagnetically controlled damping in your shock absorbers. Changes the
viscosity in milliseconds. It's available on the Cadillac XLR.
