I think the issue of the Slingshot not being enough like a car for some people is a good and valid statement, but I'll expand the thought a little more.
We as a culture are addicted to comfort and ease of living. Everything has a gadget or widget to make it more comfortable, or easier to accomplish.
The Slingshot can only be made just so comfortable. You're gonna get hot. You're gonna get cold, or wet, or dirty....and I think a lot of people aren't up for that kind of fun anymore.
So what your saying is that we all are a bunch of pus>>>>>>>>>>
