Here's how I look at it. Spontaneous fires in cars are rare whether ICE or EV. And they rarely cause death. I still remember quite a few years ago, when Audi cars were catching fire going up hills (eg. the Coquihalla Hwy), but don't recall anyone dying.
However, there are many other car defects that have caused many deaths, such as tires, brakes, ignition switches, gas tanks, unintended acceleration, roll-overs, etc, etc. But the greatest danger by far is the defect behind the wheel, whether it is drunk driving, distracted driving, running red lights, or whatever. So besides trying to save the planet with driving my Kona EV, I also want a car with the latest and best safety tech. That's what is most important to me.
I should mention that I also ride a bike (incl 3 electrics of course), and on the streets, that is even more dangerous with all the cars, some of which deliberately try to push you off the road (yeah, it's happened to me). Mountain biking which I really love is far safer, even with the odd crash (and I have had more than a few).
And yeah, I want to see the results of the Kona fire and others. But the chances of that happening with mine and killing me are statistically so low, it is just not a consideration. I put it in the same category as getting hit by lightening.
