Say a highway is a golden lit path, straight and flat, no wind.
Both drivers go from A to B covering 100 miles.
A go at a cosntant speed of 20 mph and B at 55 mph,
who will use more gas?
I don't think recharging (except for regular
lighting like a gas car) take place even
for that low-speed driver. If the low
speed driver consume less gas, it got
be only two reasons - less wind resistance
and electric motor is more efficient
at low speed
