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?
It’s easier to fix diesel buses. Not sure how we can replace batteries on electric buses. We’ll have to establish the infrastructure for that first.
