Electric Vehicles

You were right to doubt that it’s true, because it very much isn’t.

Examining electric car accident statistics reveals that occupants of electric vehicles are safer than occupants of gasoline-powered cars or trucks. For example, you are 40% less likely to be injured while using an EV than while driving or riding in a traditional internal combustion engine vehicle.

This lower risk of injury also includes the risk of a vehicle catching fire. Internal combustion engine vehicles are approximately 50 times more likely to catch fire in an accident compared to EVs — there has been one Tesla fire for every 210 million vehicle miles traveled, while an internal combustion engine vehicle catches fire once every 19 million vehicle miles traveled.

I strongly doubt that this is true.

Maybe there aren't, but relative to we heard about this already early on with Tesla, when there were way way less than 1% of cars on the road that were electric, and ALL electric cars were new, I think there actually was a higher frequency of this problem with EV vars. BUT and that's a huge but, batteries have improved a lot since Tesla model S was introduced. So it may not be true anymore.

without the numbers to back it up

This has almost seemed like a cover up to me, we've heard about a multitude of problems with especially Tesla, but it has been very difficult to find for instance accident statistics.
A couple of years back however some were released that showed that Tesla indeed is the most accident prone brand on the road in USA.
Here in Denmark we have seen completely unheard of failure rates at mandatory safety checks for Tesla model 3 last year with 35% failure rate! That in itself is insane, but this year the 2021 model Y had a failure rate of 45% 😱 The average i 8% and that includes cars of all ages, where the 2021 model Y had this failure rate at their first check that is when the car is 4 years old.

It's insanely annoying IMO that these kinds of data aren't always publicly available.
PS I bough a VW ID.4 and for that model the failure rate at the first mandatory safety check is less than 2%!!
Not buying a Tesla is a no brainer IMO, even the cheapest Chinese cars have way better record at these safety checks. And it's a similar picture for Germany, Netherlands and Sweden, so it's not just Denmark.

Incidentally a Tesla model Y cost about twice as much as mine in insurance! Which is also somewhat telling, although the companies again don't reveal the stats behind that difference in price.
