If I'm hacking something I own, it's also highly likely that I am capable of fixing it and doing any needed maintenance. Part of the hacker mindset is not letting the fear of voiding a warranty stop you from truly owning the product you paid for.

No. It doesn't matter. You can hack something you own as much as you want, and you're paying the manufacturer to do maintenance on it. If you want then to change the brakes, whether your infotainment system is hacked or not is exactly none of their business.

Hacking a linux box using USB tricks and maintaining the mechanics of a car - probably not a huge skills overlap there. But I doubt he's going to be in trouble when getting the car serviced. If he is worried he could roll back any changes before sending it in.

There's more of a mindset overlap.
