Are electric cars practical in the U.S.?

My grandpa collects old car magazines and was showing me one from the 1960s that features a car—truck?—called a Dodge Deora. It was fascinating! Were there many made? What are the chances I’d find one on the market?

I’ve always turned right at red lights after stopping and checking the intersection. But last week when I was driving in New York and did that, my partner freaked out and said it’s not legal there! Is that true?

I bought a car with an aftermarket sound system. Up until recently, it sounded great. However, sound stopped coming out of my speakers and I think the amplifier is the culprit. How can I test my car amp at home?
