If I'm reading the room, the sentiment is Honda is incompetent and their cars are security holes on wheels. But if the opposite happened, they would be technofascists locking us out of our own cars, a 30 post sub-thread "this is why I drive a 1999 Ford Ranger" would ensue, and someone would be investigating it as a possible GPL violation. Do I have this right?

It's also a good assumption most people airing such complaints have never eaten in a restaurant fancy enough to have valet parking, let alone evil valets.

That said, are evil valets known to tote around USB drives, or would they more likely use your navigation system to drive back to your empty house and clean it out while you're eating?

I think the evil valet risk isn't real, but this could be part of a chain-of-attack in some scenarios, mainly rental cars.

Like, sure, if you're just going to use it to spy on the user, you could also rent a rental car and leave a recording device under the floormat, or hidden behind the head unit, or whatever.

But if you have an Apple Carplay exploit, where someone tethering their phone to the car can be compromised, renting a car and flashing a malicious OS to exploit the phones of people who come after you could maybe be a real attack. It's kinda hard to get people to otherwise connect to a malicious infotainment system with carplay, so if you have an exploit that requires that, this could be part of it...

Except actually, no, if you have a carplay exploit, just rent the car, and rewire the USB port to go through a flipper zero or whatever and don't bother reflashing the car's software, that's just as easy.

... So yeah, I guess I agree with you, even in the rental car scenario, where this seems like it would be worst, your attacker might as well just hide something in the car instead of flashing the software.

No, this is a false dichotomy. It's not either "open to anyone" or "secure from anyone". There are various ways to ensure that only the owner can unlock the software, eg requiring a waiting period before unlocking.
