I want the new technology but it has to work like the old, and I can answer myself: Okay boomer!

I'll have to find a compromise when I finally get an EV.

How can an attacker control the steering?

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.

Get an old leaf with a new battery?

Somebody did something similar for a Jeep like a decade ago... but somehow people still expect the results to be different now.

CIA has joined the chat

::: spoiler Excerpt

Former U.S. National Coordinator for Security, Infrastructure Protection, and Counter-terrorism Richard A. Clarke said that what is known about the crash is "consistent with a car cyber attack." He was quoted as saying: "There is reason to believe that intelligence agencies for major powers—including the United States—know how to remotely seize control of a car. So if there were a cyber attack on [Hastings'] car — and I'm not saying there was, I think whoever did it would probably get away with it."

Sounds like the usual "I can neither confirm nor deny"

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

This isn’t really an EV-related thing.

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

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

I was hoping for "get an older one that uses a defunct connectivity method"

The last car I got is from 2015 so in 10 years I'll get one from this year (but not tesla).

Never buy a tesla, Elon and any employee can just watch you, hell if they really wanted they could drive you into on coming traffic for the fun of it. Majority of those accidents were not.
