Depends whether locks can be made to work.

Solutions exist within problem spaces, or "paradigms", a car lock is only useful for a specific set of things i.e. deterring thieves or unwanted entry e.g. at stop lights.

What I really want is a force-field to keep people and highway debris out while driving around, and a secure storage solution while not in operation.

If you could sell me a force-field car with a retracting tent, and it were safer/had less issues, I might not care to have locks on my car.
