#2I guess Google learned from the patent war on smartphones and they'll be better prepared against the auto industry.

#3"In one scenario, it appears, a driver is looking for a parking space and drives over a giant QR code on a street or in a parking garage. The QR code might either have exact directions to a specific parking spot, or it might link to a parking garage database of which parking slots are open."
This strikes me as ripe for abuse.

Surely the technical part is no more open to abuse than normal parking signs in cities listing the amount of available spaces in certain car parks.
The QR codes would contain very little information I would imagine but rather a key that is used by the car as an argument for further operations. Leaving all the directional data on the road would be way too easy to abuse.

Yeah. The obvious first idea is to sign the codes, but then when the private key gets stolen (100% certain to happen sooner or later,) you have to repaint every road.

Why?
Could you not have the QR codes generated against a private key and the vehicle verify it against the public key to determine whether the instruction came from a trusted source?
Just because it's plain text data in a QR code doesn't mean that it's inherently ripe for abuse.

The instruction might be from a trusted source but how do you guarantee that it is in the correct place.
How could people resist creating a loop of instructions...

I guess you could encode the GPS coordinates of the marker within it, and have the car verify that. Still not a great way of doing it though.
