Well, I think the car must allow us to shift to N under all condition.

Think about some abnormal situation. For example, you are in the far far wield field and your car is trapped in the mud, or you park the car in the
basement but the flood comes in, the water is so deep and you can't start
the car or even you can't even turn on the electric equipment.

In two of the above situation, the car has to be removed by human, not
a tow truck. If we can't shift the gear to N, then no one can move the
car.

So, in normal situation it probably fine, but in emergency or unusual situation then we need some special solution.

I will call customer service tomorrow and see what is their answer.
