Out of curiosity, when going downhill or coasting, can these motors act
as an alternator and charge the batteries?

I so beg to differ!!! You take a _very_ high performance Police
engine
and put in the 4 gallons of gas to get a normal 50 mile range
and then
go start driving it at max performance and it will go to 4 MPG
so fast
your head will spin. I drive a power wagon to get to mountain
tops and
it regularly goes from 100 miles range to 30 miles when I go
offroad.
The FIRST think I do when I need to do a serious day is make
sure it is
FULL. It would be actually easier if I was able to leave it on
the
charger every night and know that I started out _every_ day with
500
miles on the estimated range. Knowing that if I went to an
offroad
site I would actually only get 200 miles with heavy load ( and
would
actually be adding to the range going back downhill. You _aren't_
going to get stuck at the TOP of a hill with an EV..
