Also, if you browse /r/Lyft, you'll see multiple cases of drivers bragging about how they like to 3-star or sometimes even 1-star any rider with disabilities because they don't like having to provide accommodations as required by the ADA. I've even seen posters on that subreddit say "why don't they use a service specifically for disabled people?", which is especially awful because that's exactly what the ADA was written to stop. Fortunately, Lyft doesn't ban riders based on ratings, but it can negatively impact your ability to get use out of the service, as a) rating someone 3 stars or below prevents you from being matched with them again thus denying them the use of your services (and if you do this because somebody is disabled, you're probably violating the ADA), and b) it makes other drivers less likely to accept requests from you. Also, I understand that if you contact Lyft to file a complaint against an abusive driver, representatives will take your rating into account when determining whether or not to believe your word over the driver's.
