IANAL, but I think you're mistaken. Here's a document about the U.S. Gov suing 
Oceanview Motel in WildWood Crest, NJ for ADA violations:

Also, I recall my old boss choosing not to remodel his business because doing 
so would mean he would have to comply with a bunch of ADA regs.

All that said, I do think email Challenge-Response systems are a bad idea be 
they text, image or audio based. As you said, the just add more traffic to the 
mix and there are filtering technologies that do a pretty good job of keeping 
out spam. But I have to agree with you that if someone must use CR to fight 
spam, use a text based system. Even a text based system can be devised that is 
difficult for computers to overcome without intervention by a programmer.
