Bottom line if a pedestrian should be injured by a car where the automatic safety system was disabled via hack, the court is probably going to be less interested in what Nissan had to say, and more interested in what the owner did.
I respectfully suggest that you refrain from playing an attorney and giving what you believe to be legal advice, because if you hit someone in an ICE or a BEV, you are still at fault. Your argument will not hold up in any reasonable court, because if someone puts on low-profile tires on their car, that also modifies the intended performance of the car. If they change the rotors and brakes to anything besides what the manufacturer specified... same thing. In short... quit playing an attorney, because your line of argument suggests that you are not one.
Maybe I should walk over to my neighbor that has an S550 and ask him to put on an exhaust system. He even said that his car is quieter than our Leaf at low speed. When he made that "joke" I looked it up, and he may have a point. You should look up the quietest cars and you will see that "noise-makers" are not standard, but was a knee-jerk reaction because the regulatory bodies thought that we were going to drive our cars on the sidewalks.
It is astonishing that you posted so many times on this thread about this issue, and you still can't get it that you are in the minority on this discussion. Give it up and buy yourself a rotary if you feel that strongly...
You have the last word, so go ahead and make it good, Mr attorney.
