Of course, this was never about a "disability" that prevented people from sitting down. It was all about personal preference and desires, not physical needs.
If someone couldn't sit on an ECV to ride from Haunted Mansion to Space Mountain, they never could have gotten to Disneyland in the first place because any car or bus or train or plane ride would have been 100 times longer than the ECV trip from Adventureland to Tomorrowland. The Segway case was just selfish people being selfish, and tying up the courts to try and get their way. Good thing they lost.
