Electronic vehicles

Someone showed me the cool developments by Tesla Motors. That is such a sweet car. I can't wait until they make a large family car and it becomes old enough that I can afford a used version (maybe in 15 years). That got me wondering if there is a better application of an electronic vehicle that would help accelerate its adoption. I think the sports car idea is great but is there something better?
Here are the attributes of electronic vehicles:
  1. Quiet
  2. High torque
  3. Low range (Tesla is trying to improve that but for now the range is apparently about 120 miles for available vehicles).
  4. Low maintenance costs
  5. More simple system so less to go wrong
  6. Higher initial cost
  7. Low fuel costs
  8. Long refuel time
  9. Great for lower speeds and stop-and-go driving
The Tesla sports car finds 1, 2, 4, 5, 7, and 9 positive and 3, 6, and 8 negative.

Is there another type of vehicle that would find more of the attributes positive? Consider a school bus:
  1. Lower noise might help the driver hear children outside (if it isn't too noisey inside!)
  2. High torque is good for moving a heavy bus.
  3. Low range doesn't really matter. I doubt most buses go more than 100 miles in the morning or evening (for trips a diesel may still be best).
  4. Lower maintenance costs would definitely help.
  5. The simple system would be good for just about any vehicle.
  6. Higher initial cost isn't good but a school district is more likely to look at the full cost over the expected life of the vehicle so with the lower fuel and maintenance costs this probably will not be a problem.
  7. Lower fuel costs definitely help.
  8. The long refuel time won't really matter because they could easily be recharged during the school day.
  9. School buses are stop-and-go vehicles so this is a great match.
What do you think? Would electric vehicles make great school buses?

Update: I searched and found a few links about hybrid electric buses but not much about normal eletric buses. Here is a link about the Zebra bus:
