You know, regarding MB/Tesla lady, I think those reasons are just borne out ignorance, and I don't mean in a bad way; rather, that she probably just doesn't have a real situation to which to relate the advantages of EVs.
If you explain the advantages of EVs, and the LEAF in particular, it's probably difficult for people to "get it" unless they actually drive one for awhile. EVs really do grow on you in unexpected ways.
I got my LEAF at the end of July 2014. I took the car at face value: I just wanted something affordable to replace my aging Silverado (MY 1999, ~190,000 miles), which I wasn't really using for hauling things anyway. I found out I could lease the LEAF for almost the price of the gas savings alone. Environment and clean energy played absolutely no part in my decision to get the LEAF. I did have some concerns about recharging, but I was willing to take some of that into account to have something convenient for commuting in traffic.
However, over the last 6 weeks, my reasons for driving an EV have really shifted. I discovered that I really appreciate the quiet ride, the odor-free transportation, the ease of use and ease of maintenance, the absence of any further trips to the gas station (what a pain!). It feels liberating!
I remember the "dark days" pulling out my credit card at the pump, and wincing every single time. And I was going through that motion once a week.
With the LEAF, driving became fun again. I realize today that I couldn't drive another ICE vehicle again. I had always wanted a Mitsubishi EVO (I like performance), but I will gladly wait now for an AWD electric (or the Tesla Model 3). That would be cool.
My point is, though, that I don't think you "get it" until you drive an EV for awhile, and then you won't ever want to go back again.
