I used to ship a ton of First-Class parcels and Priority parcels about 10 years ago, and learned that they had roughly the same delivery speed (2-3 days anywhere in the contiguous US) with First-Class just having a higher chance of delay.
As I never paid attention to letter delivery speed back then, I didn't realize that letters are much slower (except local). So seeing these maps today is informative.
Fortunately, removal of radar will reduce the frequency of phantom braking, so hopefully this habit will fade.
In my experience, that warning about not braking occurs when you are in TACC mode but are pressing on the accelerator to go temporarily faster than the set speed.
Power dissipated by resistance is only linearly (not quadratically) related to resistance when current is relatively fixed: P=(I^2)R. So reducing the parasitic resistance from 180mΩ to 68mΩ is only a 2.6x improvement, albeit still quite significant.
