Answer 1

Highway you’re going the same speed for a long period of time generally. Cars are fairly efficient for fuel when cruising about 60mph. Fuel is used up most when accelerating which you don’t need to cruising at highway speeds.

Electric vehicles can generate energy through braking, since you don’t do a lot of braking when cruising, EVs suffer as they cannot generate the energy from the stopping and starting.
