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 pick

What you're describing about your pickup is the balance of weight, not the total weight.
- Skunkleton 7y agoYou 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.
- zamfi 7y agoHah, 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. > For example, you might find that your car is blown off the road by a light breeze. We should be so lucky! An EV as light as a bike...
- rootusrootus 7y agoI wonder where the danger point really is. I've driven some lighter, smaller cars that were borderline dangerous in a stiff crosswind.
