Of course people parking their ICE vehicles under, in, or near where people live is completely normal and socially acceptable. Even though they do occasionally burn.
And when I say occasionally, I actually mean: vehicle fires are most common reason for fire trucks to be called. And the overwhelming vast majority of those fires are good old ICE vehicles catching fire. That's not news because the media would be in a permanent stat of OMG, another one burned down hour more or less 24/7 around the year. If you think that is exaggerating things a bit, The US actually has hundred of thousands of vehicle fires reported per year causing billions in damage. And a year is only 8760 hours. You might want to consider your fuel bomb on wheels a bit further from where your loved ones reside, just saying.
Batteries are mostly safe. There was (past tense) a problem with low quality cheap Chinese e-bikes using unsafe and uncertified components. That already is being addressed through stricter regulations and tariffs. For the same reason, the TSA is now completely fine with you bringing phones and other battery equipped electronics on planes.
Home storage systems are far less problematic and usually involves professional electricians and using quality components from very responsible manufacturers with stellar reputations. I'm sure there are some isolated cases of these things having issues. And I'm also sure that that's not going to be a huge number of incidents. And that that pales in comparison to the statistics on gas boilers/furnaces, ICE vehicles, etc.
The (mock) outrage here is very selective and targeted. There's a crowd of fossil fuel funded lobbyists out there promoting any article that serves their agenda. They drip feed news papers, magazines, etc. with a non stop flow of articles to promote their agenda of spreading FUD about EVs / renewables.
I'm sure this is otherwise a fine article. And maybe somebody even is peer reviewing it; the site wasn't very clear on that (other than the 0 citations statistic). But is it really that interesting / world shocking? Why does dry bit of otherwise completely uninteresting statistics literature end up featuring on the front page of HN and getting tens of thousands of views?
