Nope; and I wouldn't. I want some protection around me. I have a 2010 Ford Fusion which I get 24 MPG around town and that good for me. Last year we had snow and ice and someone thought he could drive one of those in it; he hit the ice and litterly slid straight across 4 lanes of traffic up over the curb and straight into the cement wall. To say the least it was a lot flatter than it already is.
I can see getting something besides the van; there are so many cars out there that are safer to drive and some that have dual fuel besides the ones that also use electricity that also offer some protection between you and the what's on the outside of the car. Rather that be a stone wall or an on coming car.
