Why? This sounds like a nice upgrade:
The truck comes equipped with air suspension, allowing its height to be adjusted to four different levels. It’s all-wheel drive, unlike its predecessors, and being electric, there is more space for storage.
And the article says it has a fallback diesel engine if the battery runs low:
According to the city, it also has an onboard diesel engine that will automatically engage when the battery drops below 20 per cent during an extended firefighting response, ensuring no breaks in service.
I'm honestly not against this. I know a lot of people will be furious with Mozilla about doing anything related to advertising, but as the article says:
We may dislike ads, but the vast majority of internet users are not going to engage with content that requires you to pay up front. Creators and journalists need money to survive, and currently, ad-supported viewing is necessary for that to happen.
Instead of just hoping that advertising somehow goes away, I'm glad that Mozilla is working on ways for ads to exist without mass individual user tracking. I wish it wasn't necessary, but wishing won't change the world.
