weight of the car

strong magnet

but there is no magnet that can move a 4 ton chunk of steel

just make one

here's the issue
I can't I am a tactically advanced MTF member not a f**king magnet scientist

you know how magnet crains work right

No

However, the magnet would be pulled back and since it is attached to the car the car would be driving backwards, weren't it for the fact that the car should already be moving forward, therefore cancelling out.

My wee brain hurts trying to comprehend that.

Magnet on front pulls. Magnet on car pulls. Both pull against each other. Stalemate.
