I wonder if an area with steep hills is the best place to use a hybrid. On
the one hand you can recover a lot of energy going down the hill, on the

hill. If the route goes that way of course.

That's one thing. Another thing is when crawling in traffic the engine can
be (and is on London hybrids) turned off completely, leading to less wasted
fuel idling, and less pollution at the point of use.
