How do you propose to build something like that where it’s actually limited to just emergency workers?

This is like the fire keys for elevators. You can find them on eBay.

It doesn't sound difficult to solve. The sensors can classify firetruck, ambulance, red&blues, uniformed police, badge, siren, etc. At a certain criteria, they can unlock the driver door for normal human driving, perhaps for a very limited speed and distance. The officer can move it to the side, and if they crash it's not waymo crashing it. This override should send the an alert to the remote command center, so a human can watch the video and also decide how much further they can drive it. Since passenger safety is a concern, if there is a passenger inside who chooses to remain inside, the car should remain locked and not allow any driver in. The human can decide to follow police orders to exit the car, or remain inside, but at that point a human becomes responsible for obstructing. The whole freezing waymo trend seems driven by legal liability - not engineering. They know if they always freeze, their million miles with no accidents stats are safe.

Cops can't move vehicles that they don't own because of liability. The only way for them to move a vehicle without liability is to use a tow truck.

First thought would be to have the remote human over watching to engage with an emergency responder when the override is used. The remote human can then decide whether it is a real emergency or not. Either way, if any one uses an override system, a remote human should get involved. But instead, computer devs will suggest crypto/public/private keys/blahblahblah. This is one of those where the best answer will be to boot up the bio computer running the latest software

It's not too hard to implement them with cryptographic protocols to prevent duplication and apply time/location restrictions to them. Moreover if you really wanted to steal a car, there are much easier ways of doing that, like buying a replica gun on aliexpress then going to your nearest intersection.

The problem is not really that they can get stolen, but remote control, like a bad person gaining access to the car to hit people or something like that.

And every single day you hear about someone abusing them right? Or no?
