Well the very first thing you need to do is get a lawyer. Depending on how long those crabs have been in there, they may have some sort of squatters rights from inhabiting your car. It's tough to sue a single crab, its extremely tough to sue 60 crabs. Assuming they haven't broken anything and the car is still working, you probably won't be able to get the police to deal with them because they don't want to get snipped at over nothing. You are going to have to lure them out yourself, and then once they are out of the car then you can go after some kind of civil suit against them for holding your car hostage. There are many ways to remove crabs from an affected area, but your first step should probably be to play Crab Rave over a loud speaker just out of sight of the car. The crabs will become interested and scuttle over to investigate. You can sneak around them and book it to the car and drive it away from them.
