The ADA has dramatically improved accessibility for those with mobility impairments:
" When asked whether access to public facilities had improved, 75 percent or more of respondents in 1994, 1998, and 2000 reported that they had perceived improvement. Not surprisingly, the percentage of people with disabilities going out to restaurants regularly has increased from 34 percent in 1986 to 57 percent in 2004."[0]
