I remember having to plan around the expected number of cabs that wouldn't bother to show up after quoting "10 mins" to get to SFO. Or having a London cabbie decide that my being sat in his cab was a license to spout pro-Brexit nonsense for 15 minutes and then claim that he didn't take credit cards. Or NYC cab drivers blatantly flouting the law by purposely ignoring you if you had a suitcase, because they didn't feel like taking a fixed fare in traffic to JFK.
No.
I think you're in the minority. And remember that the subsidies went both ways - one reason Uber was able to attract so many drivers initially (and thus provide great service) is that they paid them more than driving a cab would.
That is indeed how much Uber cost when it first came out. Particularly because they sent out nicer luxury cars and had to hire limo drivers. Uber used to be called UberCab, but the medallion cartel didn't let new entries in so easily and forced the change from UberCab -> Uber, and also made it so they had to use luxury limo drivers. Still, users chose and taxis died, rightly so.
The unit economics are there that whatever Taxis charged Uber should be able to charge the same or less. If anything Uber et al are removing overheads not adding to them. The only way taxis would be cheaper would be if they were dodging taxes with their "no credit cards" policies.
Selling a good at a loss in order to jack up the price later (the desired Uber play, though it seems like it's backfiring) used to be called "dumping", but...eh.
