More so that ICE has really bad efficiency at city driving due to lack of regen braking and engine idling.
EVs (and hybrids) with regen braking remove this lost efficiency in city driving, leaving you with an energy usage curve that scales more directly with aerodynamic drag due to speed.
EVs are more efficient at low and high speeds than ICE, they just have small “gas tanks” so the high speed losses are more noticeable.
ICE engines have an efficiency map of output torque/RPM and (up to a point) higher torque usually means more efficient use of fuel. In most ICE vehicles the engine efficiency gains balance with the drag efficiency losses between 40 and 50 mph.
There's quite a lot of energy needed to just turn the engine over in an ICE car so if you are driving a 5L car at 20mph most of the fuel use is just turning the engine rather than driving the car. Faster, more goes to driving the car.
