I'm sure I'm not the only person seeing ads from Uber to use my own car for extra income. For the record, I haven't signed up.

My own car is not wheelchair accessible. It is spacious, and could fit a collapsed wheelchair. But I don't have a lift. Even if I were to sign up as an Uber driver, I can't say that I'm a kind enough soul to add a wheelchair lift or other equipment to make my car wheelchair accessible.

I might be willing to do so for the right incentive. If Uber were to get me a discount on the modification, or promise to buy my car from me when I no longer want it, or give me a higher percentage of the fare when I pick somebody up, etc. But I, personally, wouldn't foot the bill for purely altruistic reasons.
