A peripheral benefit of electrified buses would be regenerative braking.

I've lost count of the amount of times that grubby, dusty brake pads have led to screeching that makes me feel like my ears are about to bleed, when buses have come to a standstill beside me. I once even wrote to TFL about the problem, weird little man that I am. Never received a response.

You're not the only one bothered by that. I find school buses and small delivery vehicles to be the worst on that, given the frequent stops and starts and minimal maintenance they receive. The city buses here are marginally better but not by much.

This drove me insane with poorly maintained NYC taxis and buses too.
