These would not be problems if the car software&#x2F;hardware is properly constructed. The issues with the odometer, alarm and doors could be solved by signing the relevant binaries&#x2F;data with a digital key. The issue with the bus connector is close to negligence in my non-professional opinion (the fuel cap is locked on my car as is the switch to release the bonnet).<p>The security by obscurity argument is pretty dead at this time -- it doesn&#x27;t magically get resurrected just because the object we are securing is a car.
