Don't know where you're from, but for Germany this is mostly solved, but those tactics are obviously still "new" for most and need to be refined, yes.

edit:

> They do require a lot more water to be put out though.

As OP was mentioning garage fires, I was expecting urban neighborhoods, where getting enough water should (hopefully) not be a problem in 2021.

German here as well. For the Berufsfeuerwehr (for the Americans here: professional, full-time firefighters in big cities) yes, for Freiwillige Feuerwehr (volunteers, mostly in rural areas) not, which has been the subject of numerous media articles (e.g. https://kommunal.de/feuerwehr-fehlen-einsatzkraefte).

I was talking about electric car fires in general... and in rural areas, that is a problem (see e.g. https://www.nordkurier.de/uckermark/kontaminiertes-wasser-be...).

Anyway I'm not interested in fearmongering, just pointing out that even in Germany the situation isn't as decent as one might hope - and the US is even worse off.

I see you haven't lived in a mega-city like Karachi. When I lived there (some years ago, admittedly, but I don't believe things have improved much) we were lucky to get mains water for a few hours a couple of times a week at some seasons.
