Selling a car with intentional root access would almost certainly be illegal in the USA, and most places.
Cars have government-mandated safety features, and manufacturers are forbidden from adding kill switches. Selling a car with (manufacturer-sanctioned) root access would be legally the same as including a kill switch letting the owner disable safety features.
If an owner cuts their brake light wires to flee the cops, it's 100% on them. If a manufacturer included a switch for it, they'd be in massive trouble.
