Indeed F = μN, but also F = ma, so you don't need as much F to accelerate a lighter vehicle (that is, one with lower m).

What you're describing about your pickup is the balance of weight, not the total weight.

You are forgetting forces to overcome effects which are independent of mass. For example, you might find that your car is blown off the road by a light breeze.

Hah, yeah, an earlier version of my post said something about external/edge effects as you approach 0 mass, but I didn't think it was germane to my main point.

We should be so lucky! An EV as light as a bike...

I wonder where the danger point really is. I've driven some lighter, smaller cars that were borderline dangerous in a stiff crosswind.
