I hope to approach this solution using muscle wire and resistive fabric. When the driver sits in the car and turns it on, their weight pushes a series of resistive fabric buttons within the seats. This causes current to flow to the muscle wires, hence hugging the driver tighter. This tightness could be based off the mode the car is in (comfort, sport, etc.). In a sportier mode, more current could flow to the wires causing a tighter grip, while in comfort it would be less.
