It also might be possible to control the pumping of liquid fuel, but I'm guessing we wouldn't want to carry liquid rocket fuel.
I think that's a very shrewd guess!

If we could maintain 100psi pressure differential in a chamber with a 10 square inch nozzle we'd have 1,000lbs of thrust.
We need to do some calcs, but that's an awful lot of compressed air. Having said that, with something akin to a couple of SCUBA tanks mounted over the rear axle, and a small engine-driven compressor to charge them you could store a fair bit of air. Thinking about it empirically, I've once seen a compressed air welding bottle that fell off the lorry and knocked the valve clean off, turning it into a jet. Let's just say that there was no shortage of thrust!!!

So what can we do to make the wet road behave more like a dry one. At the moment the only thing we do is cut tread into tyres.
The front tyres squeegee a track for the back tyres to run in. If only we could reverse the weight transfer effect and do most of our braking with the back...
...which is of course just what our "C pillar 45 degree retro jet system"
tm would do.

I wouldn't. Adding downforce to the rear doesn't reduce front axle load, in fact it increases it. If we put 10 tons on the rear axle then apply the rear brakes up to the new limit of adhesion the torque reaction acting around the rear axle would load the front wheels right up again.
