It's cleaner. So that's good. The problem is that the batteries on electric buses are not going to last a long time. I assume 5-8 years. Then how do you replace the batteries. This is government we're talking about. With diesel buses, you can get 20 years out of them.
Yes, good point about the life of batteries. Overhead wires and bus pantographs didn’t have that problem. I recall the faint odor of ozone from the arcing wires, too.
The maintenance cost of diesel buses must be through the roof. Hopefully it’s a lot lower for battery buses.
When the battery buses catch on fire, how do you find a dunk tank big enough to submerge the entire bus?
