I happened to be in the Bay Area for a board meeting when the Get Amped tour started, so I did get to test drive the car. But I absolutely would have purchased one without a test ride. I mean, I wouldn't have purchased the first one off the line with no independent assessment, but the early reviews from magazines and the first owners were plenty for me. It's way nicer to drive than I need, so there was no go/no-go purchase information to obtain from the drive. The car just had to drive adequately; I was largely interested in finding a good long-range EV (both our cars are EVs, so one has to have really good range), and there were no other choices. It helps that I'm pretty average size, so I don't have to worry about fit issues.
Same thing with the Roadster - there was no store here at the time, and I would not have traveled to test drive one. I was ready to buy after reading some magazine articles and talking to a local owner that I ran in to. As it happens they had just hired a local person that had a test car; when I started asking questions, he brought it to my house and I drove it. But I had already made the purchase decision.
I've purchased plenty of previous cars that way, too. I bought a used 2003 Toyota RAV4-EV from Utah without ever having seen or driven one. I bought a used 2005 Honda Insight from Utah (just chance!) without ever having driven one. I bought a 2000 VW Golf TDI online without ever having driven one. But in all cases I was buying petroleum frugality, not driving experience. It's really nice that with EVs you can get both.
