A company designs and builds a car to safely drive at 70 mph.
You drive at 140mph in the rain, hydroplane and lose control hitting a bridge column, and die. I'd say the fault lies with the driver. What about you?
Said company puts in an ignition switch that's faulty and disconnects the entire control system while driving at 70mph and ignores reports of this problem for a decade. That would not only be the fault of said company, but adds layers of premeditation still to be decided.
A company designs and builds a car to safely drive at 70mph.
They spend lots of time and money showing pictures of the car on a race track and design the interior to make it feel like a race car.
The default position of the gearshift when pulled down disables all of the speed limiters and briefly flashes a "Race mode" light that, if you read your owners' manual, indicates that you agree to not hold them responsible for anything.
A complex procedure drops you into "street mode" which baffles the exhaust to legal levels and enables traction control.
When someone drives at 80mph and wrecks, the car developers act surprised and alarmed that anyone would be so irresponsible.
