I would strongly suggest that Voyage look into finding vehicles to adapt to autonomous that people can walk into.  Being able to walk into a vehicle (like a bus) is easier on the body and speeds up entry and exit for any age person but especially for 55+. I could see a much higher buy in by seniors if this element was taken into consideration and if one of every five vehicles had wheelchair/handicap access ability even better. Going after only "active" seniors is really limiting your market in retirement communities.
