There appears to be some efforts being made to address some of the issues raised in this thread, especially the "drive-by" law suits against businesses that don't provide ADA access.
HR 620 is now in the Congress. Basically, it sets up an education program for business and disability advocates to improve compliance and understanding of ADA regulations. More importantly, it establishes a procedure that must be followed
before civil litigation can take place. This procedure states that if one is to complain about non-compliance of a business;
“(i) that person has provided to the owner or operator of the accommodation a written notice specific enough to allow such owner or operator to identify the barrier; and
“(ii)(I) during the period beginning on the date the notice is received and ending 60 days after that date, the owner or operator fails to provide to that person a written description outlining improvements that will be made to remove the barrier; or
“(II) if the owner or operator provides the written description under subclause (I), the owner or operator fails to remove the barrier or to make substantial progress in removing the barrier during the period beginning on the date the description is provided and ending 120 days after that date.

Seems like a good bill, to me.
