GM has done a nice job overall to make the car similar to our everyday driving experience, with subtle touches to let you know you are driving a fuel cell car (the graphic display of the process, the tachometer that reads in KW vs. RPM, the display info, etc.). I echo Dave’s comment about more info on the display, but I think that’s because we are interested in that kind of stuff – others who drive it may not care as much.
I was surprised at how interested my son’s teenage friends were in the car, asking for numerous rides. These aren’t the kind of kids I would have thought would be interested (they are the prototypical school jocks) but they were asking a lot of questions about where we get hydrogen, how much the car costs, how does a fuel cell work, etc. and of course liked the acceleration. When I told them it only emitted water, they immediately went to the exhaust vents and sampled the emissions in true teenager fashion.
My overall impression of the car is great, and other than the range could see how these could catch on with the general public.
