The free market is surprisingly efficient - in other words, ruthlessly effective - at eliminating money sinks. Like passengers with disability, which are only tiny part of client base (and not too wealthy a part) but require special adjustments to cars. I don't see how fully deregulated taxi business would do anything but ruthlessly eliminate them from the client base.

Yes, maybe we could use little less regulation. My personal issue with Uber is not the concept of less-regulated taxis. It's that it's managed by a bunch of sociopathic assholes, who openly try to exploit drivers and the community for profit, painting themselves as white knights while using every underhand tactic they can get away with to sabotage competition.
