Code audit time?
Considering this case of VW (and no doubt others) lying in such test.
Toyota with unintended acceleration (and a few deaths) due to poorly design software
Ford with cars that would not shut off.
Others like Jeep with crappy security where in-care entertainment could fiddle with braking, etc.
it seems it is high time that on-board software was treated as something to be subject to an independent audit to establish that it is not cheating in test (that any "saving features" really work for normal driving) and that safety and security is taken seriously.
