As you wrote, and I agree, the designs are improving. I am not against EVs, I think we should wait for all the glitchs to be resolved before moving forward in our instance. On another note, we here in Quebec are fortunate to produce our electrical power by water powered dams, very clean and efficient, so an EV vehicle is a super choice for our environment. However, in places like the Central United States, coal is the primary source of energy to produce electricity. With a huge population of EVs in their locale, how much more coal has to be burned (and increased pollution) to support the present day requirements plus an influx of EV charging stations. Not such an efficient choice now.TBH, I wouldn't lose any sleep over issues with an EV as they are quite rare. My wife is considering buying one for her next vehicle. For the most part, the dangers are minimal and designs are improving. Don't forget, all vehicles are very toxic when they burn. One issue with ICE vehicles is the fuel. If the fuel tank fails, then the flames will possibly spread to anything nearby as the fuel leaks out and most fuel tanks are plastic these days on passenger vehicles. Any lithium battery (including the one in your laptop, phone, watch, key fob, etc...) will burn uncontrollably and we cannot put those out either. Lithium batteries are very common and we accept them without a thought to the dangers.
Also, in high crime areas, how do you plug in your car overnite and hope nobody tampers with the connection?
