There are also lots of options for disabled folks that aren't all the way to a car. My wife and I bike around our city daily, and there are plenty of disabled folks zooming around on all manner of mobility devices, in the bike lane, on sidewalks, at similar speeds to bikes. I'd argue that making a city more bike friendly also makes it more friendly to these types of mobility devices as well. It seems that these two things, bike friendliness and disabled friendliness have the same needs of our infrastructure.
