I find alot of people take pictures with their cell phones while driving, but relatively speaking I haven't had alot of people come up to me and ask me about the car directly. Maybe that is because I have gotten so use to the extreme attention from people when I drive my 10 year Orange Sparrow. Anyways, the funniest thing is when you are at stores or restaurants, listening to people talk about the Roadster as they are coming in, because they don't know whose car it is they will say just about anything. Of course almost everyone comments about how beautiful the car is and I am always surprised how many people know what the Tesla is all about. In my Sparrow, I still get asked more times than not how many miles per gallon I get, whereas I don't think anyone has ever asked me that about the Roadster. Very few strangers have been bold enough to ask for a test drive.
Anyway, the attention is always fun and if it helps the EV cause all the better.
