It is not just EVs, this can be done on almost every new car in some form or another.

Install the latest update and hope for the best.

Or try disabling bluetooth.

Or try to get a car without autonomous parking.

Seems like there is no real option though.

This isn’t really an EV-related thing.

I think there's a few options, in order of increasing cost:

• get a really cheap one from ali express or similar
• get an older one that uses a defunct connectivity method
• modify one to remove/replace any telemetry modules
• build it yourself from scratch using parts from ali express or similar
• get a shop to build one for you

Get a used moderately old petrol car and do an EV motor swap into it.

Remove the modem. When I was researching chevy bolts that was the first video I looked up and there was a guy walking through it. It involved opening up the panels and was time consuming but I was willing to do it. Unfortunately, didn't end up getting a chevy bolt.

Edit: sorry, I didn't read it and it appears to be bluetooth or radio frequency. Removing the modem would not prevent this attack. Probably update the car and hope for the best. Unless you figure out how to remove rf and bluetooth

Get an old leaf with a new battery?

...a semi-autonomous vehicle surveying a dead landscape?

Bluetooth -> infotainment system -> CANBUS -> Lane Assist or adaptive steering

Die infotainment system should not have this permission, but it does.

The loophole is the connected smartphone from the driver. An attacker could deauthenticate it and mimic the car app.

Lots of modern cars have electric power steering. Many of them have lane keep assist.
