The drive is inside the car. How do they get at it, and guarantee it isn't tampered with in the meantime?

They have Tesla (the company) unlock the car, then remove the drive. They already have the search warrant, which could compel Tesla to assist. They have a cop babysit the car until the seizure is completed, like they have to do anyway.

Sorry, but towing is much easier than dealing with Tesla's lawyers.

But Tesla should add remote wipe too, just like with iPhones.
