It's not like a scarlet letter... You are not required to have a disabled placard if you are disabled... only if you use designated spots.
Plus, limited mobility does not always mean "handicapped." Maybe deteriorating joints limited how high the leg can lift so a low step is needed.
The 4Runner is great for more than ground clearance and off-road capabilities. Maybe they just wanted the size, reliability, and style even if they sacrificed some ground clearance...
