I think that there should be two types of vehicle locks. Or one with two options. This way, you could, lock the wheels of a bike so that it does not move. Much like the ones used to lock one to a bike rack. But there should also be an option to build a lock that would keep people in/out. That would allow them to be used as storage containers. Or prisons!

The way locks work now, they could be moving prisons. I'm tempted to use them for that.
Imagine a mass murderer stuck on a tandem bike. But wait, that would mean he could flee faster. And not be able to be dragged out. Hmm... We need wheel locks!
This could also apply to other vehicles: boats, cars, etc.
P.S. - wheel locks would also apply to the ignitions of cars and oars/sails of boats
