For the constant stopping and starting these vehicles do, it does seem like electric would be perfect. How many miles a day does a typical mail delivery truck run? Let say the overall average speed of the truck through out the day is 10 mph. That puts in in the ballpark of 75 - 100 miles/day. Given that it's all stop-start movement, that would probably exhaust the battery pack that comes with the Model S. Regenerative braking would help, though. Seems perfectly doable. Feel free to correct my napkin math. I could be off quite a bit but Fermi-wise I think I'm good.
