Override would have been great.
I understand the idea of taking all of the work out of shifting, but putting the option there wouldn't have been a bad idea.
While you're at it, plop a spedometer on there, computers are cheap nowadays, and would be cheaper still if you integrated the circuitry into the Auto-D Computer.
That said, while it is a noble goal, I don't know how well it will work. I've ridden a lot of different styles of bike, and indeed by far my most enjoyable one is my internally geared bike, I LIKE having something that requires some input. I'm probably in a minority
Mechanically speaking, though, 3 speeds really isn't enough for some hilly areas. I would rather have seen at least 5 speeds on such a bike. This isn't a car, you're going to REALLY feel the fact there are only 3 speeds. I'm also in agreement about how a coaster brake is not the best call... but customer opinions win out... I have seen lots of customers who don't get a bike because they want coaster brakes.
