Electric bus fire today! Why?

Electric bus catches fire in York today.
What worries me is that they are carrying on using them without knowing the reason why the fire started!
Good job Boeing didn't take the same approach when their 787 was having battery issues

We've had a few of our London diesel buses catching fire and burning out, here's one report with photos.

Fortunately none of our hydrogen powered ones have gone up yet!

Cars and trucks and diesel buses catch fire too. At least you can get off a bus if it starts to combust. Not so easy with an airliner at thirty thousand feet.

Crossed with the above.
