The response time requirement could create an interesting tension between ADA proponents and environmental advocates. That is, if Uber/Lyft need to have vehicles that are 2 minutes away for passengers with motorized scooters/chairs whenever they have vehicles that are 2 minutes away for ambulatory passengers, this will require having many larger vehicles. These vehicles pollute more (and if they're EVs some day, they'll draw more electricity).
In my experience, only about 5% of the rides I've had end up being on vehicles large enough to stow a motorized chair, so equivalent response time could mean a major shift in the type of vehicles used.
