From the mid 19th century until the early 21st century technology has changed many things.
The question that is bugging me is why are wheelchairs not one of the many things changed beyond all recognition by the technology available - the equivalent of model T Fords is still standard fare - why ?
It should not be price a powered wheelchair costs as much as a small family car while using technology suited for the beginning of the last century. There is as much thought about the contents carried as goes into a sack barrow - something that really matters with chronic pain, you really don't want to be able too count the cracks in the pavement.
