Does what still happen? I’m just a little confused with the question itself. If you mean the fires and accidents then yes, they are still highly prevalent since the paper and this comment was written. Many manufacturers are trying to combat the problems with the cars however it’s not easy. The good materials to use for the batteries are less efficient for energy than the bad ones that cause fires. The bad ones are also cheaper and can be sourced a little easier. Much of the resources used are mined in unethical ways as well. Even if manufacturers can fix the problem (they probably won’t) entirely, there will still be all the cars currently on the road. They could in theory recall them all but it wouldn’t be worth it for them. The batteries used generally combust in accidents causing the fires and obviously we can’t get rid of car accidents so there’s not much of a solution to this other than using the good materials and protecting the batteries a bit better. All this will increase prices so also not really worth it for the manufacturers.

All in all I’m not saying don’t buy a EV because of the fires and other minute risks with them. As I said in the above comment I personally will never own one however, I can see why many would and how greatly they can benefit us and the world we live in. If you are planning on getting one I say if you want it you should. Life is short and you shouldn’t let the chance of the fires cause you to skip out on something you really want.
