Sounds very cool indeed, Diabando.
Why not make it an outside lock and switch (hidden ofcourse) or remote control and expand it to your doors as well?
An airline to every door and an extra air driven three-rod lock, like a vault.
Optional a locking rod through all the pedals, through the handbrake and maybe four rods, drilling itself inside the tarmac whenever parked just to secure being towed away.
