I don't see the need for a specific section for electric car discussions here at Amiga.org. It makes sense that folk interested in Amiga might take an interest in other techy topics from time to time. You can't talk Amiga all the time, and the ideas of Amiga folks interest me more than some j.random.nerd. That's what the generic tech forums are for. Start a thread there...
Having said that... electric cars are premature. There's only one part in them that isn't mature tech... and that's the battery/power source. We've been building the mechanical parts of the car over 120 years. Electric motors are older than gas engines. When you have an electric that can recharge in 10 minutes for a 400mi range or doesn't need enough platinum in it's fuel cell to stock Tiffany's, then call me. ;-)
