2. Electric semi trucks are not ideal for long distance trips, they're more for predictable day routes, so it wouldn't surprise me to not encounter many of them on what was presumably a highway drive.
Disagree. All you have to do is look for lack of a front grill or flush door handles to tell if a car is an EV.
