Peri,
It is obvious to anyone that has attempted anything like this in the real world
with real parts that a vehicle will be more efficient on level ground than with
hills. It is only in a theoretical world and using math that you can create
and drive a hilly route and do it as efficiently as a flat level route. There
are inefficiencies in the real world that will present a greater loss going up
hill than you will get back going down hill.
