This is exactly how they remove vehicles from the streets of London which
are illegally parked. They have a flat bed truck with a device like a
container crane that lifts the car up onto the deck. They are well rewarded
for it - the parking fines come to more than the value of many older cars,
especially if you don't get the vehicle out real quick :)
