Toyota has posted a 2 minute virtual drive with the FT-CH concept over on YouTube (you can see it below in HD). The video overall is very cool with a great soundtrack, but I've never seen a gas station in a tunnel before (and I don't think it would be safe). The final 15 seconds has a nice "Welcome to the family!" moment.
If the FT-CH is less espensive than the Prius and if it gets better mileage than the Prius (both of which I think are true), then it looks to me like Toyota will sell them in big numbers. I would go so far as to speculate that they will sell more of them then the Prius in 5 years.
