> Citroën hydraulics are detailed but not that complex
Have a look behind the left hand front wheel cover panel and say that again :) There has to be at least 50 meters worth of high pressure line behind there and a functional analog computer using hydraulics. That's what keeps the car balanced front/back and left/right. The height adjusters just do the static balancing for load, that thing on the left front does it dynamically with a response time in the 10's of milliseconds and keeps continuous track of what 'level' means to the car occupants. It is a very impressive piece of engineering which has some components that will leave you completely puzzled (a tube with a few hundred metal plates in it with a tiny hole through the middle, for instance) if you don't know what they are for.
