I've gotten the "Is that a new Tesla?" a lot, as well as the, "what year is that?" and "How do I buy one?" (I'm in Texas.)
Every time I say, "it's a 2008" or "it's 7 years old" and "the only way to get one is to buy it used," people have a hard time reacting. ('But... I... they made ELECTRIC CARS BACK THEN?')
My favorite, though, isn't the stupid questions. I love it when people know what it is, and they say, "wow, I've never seen one in real life before!"
I also like it when people ask me about electric cars in general and say they're too expensive, and I tell them that I also have a Leaf and just about everyone who owns a home with a place to charge an electric car can afford to pay $199 a month to lease a Leaf -- $199 a month for a car you don't have to buy gas for should be exciting.
That gets people thinking beyond the ICE.
When I drive the Leaf around, I very, very rarely get stopped by anyone with any questions. Though it has happened on occasion, at charging stations.
