I sort of remember the Roll Fast as I had one years ago. The thing I had not seen much any of is that two parallel bars that start at the stem and go past the seat tube to make sort of a rear luggage carrier platform. From the picture I cannot quite see if any sheet metal widens the area for a carrier but it could be added.
Maybe that specific is an indication that it is different than many other makes. I shall try to see if Google has a way to have a picture scanned to do the leg work, They already have put a self driving car that got the guy behind the driving wheel (but not touching pedals or wheel) to get the guy and passengers onto 101 North Highway Entrance near there headquarters. The thing on top (looks like the other thing they have for ground images for Google Earth) uses I think LIDAR. The crunched data in a computer on board to drives itself. You have the option to take over when you see fit though!
The DARPA Grand Challenge is no more, but why not have silicon do the driving? Too bad the Grand Challenge did not include two wheel vehicles, but a self balancing motorcycle was there attempted and also disqualified. It did not do too well, but hey get whatever that frame you got and get a working motorbike, and then you can start on building a reclining seat as you will be the rider, but not the operator!
