Not sure how it works in Paris/London, but the other day I parked behind a gigantic US style pick-up. That monstruosity was longer than the parking spot, but also wider with like 10-15 cm on the street. This is messing with cyclist, car on the road, but also people who want to park behind you and don't have the usual reference.
Seriously, if you don't fit on a parking spot, you should be towed away. If you want to drive a truck, go in a truck parking which are usually in industrial area away from the city.
