> On my friends car you had to put the key to ACC, then turn the cruise control on and off, and then engage and disengage the parking brake before the car would start.

That’s a cute trick, but if a current day equivalent is integrated into modern day cars (i.e. CANBUS-based), then the security is already defeated.

No one challenged the security of the “cruise control cheat code” of the 1990s simply because there were no devices small enough. The other bit is that criminals weren’t sophisticated enough.
