if your car kills your kid, eg the airbag misfired, or the lane assist went into oncoming traffic, then the car vendor will look for any opportunity to evade and refute responsibility. including claims of self tampering with the car. now in the burnt wreck, forensics need to show beyond doubt that it was, indeed, the car vendors shipment that killed the kid. how do you show as DA, that indeed the software was untampered with?

ps: airbags not working is less of a software problem than airbags misfiring.
