There’s still the battery problem. One of Tesla’s big innovations was the switch to lithium batteries and they started out by trying to design a battery pack that wouldn’t easily catch on fire. As we now know those efforts were mixed at best. Earllier electrc hybrids like the Prius did not use lithium.

Its a strange problem when the costs are dropping constantly, virtually month by month, and the power outputs of the batteries are going up all the time. The price of lithium has actually being going down, contrary to scare mongering about supplies.
And yes, lithium is flammable. Just like gas and diesel is flammable. IC cars go on fire every day somewhere, its so common it never hits the news. One colleague of mine, who had a fondness for driving old Saabs and Mercedes, had 2 cars burn up over the course of 10 years, both electrical faults.
