At least in Portland, I've never taken a taxi in my life, but have taken probably a dozen Ubers.
Which is one reason why Uber is winning. You do not even bother to check taxi fares.
I checked Uber rates to get to the airport. Not cheaper than taxi - about the same.
Did people stop tipping cabs?
Maybe you meant Ubers were 20% more expensive, or maybe people don't tip cabs anymore, I don't know.
Honestly I'd pay more than cabfare + tips just to have the price be explicit. Tips basically become a tax on nice people. I'd much rather everyone was paying the same price.
When I first got here, I used Uber all the time, but the government passed some anti-über laws and Uber withdrew from the market. Now I just use the public transport, which is pretty good, but less convenient than Uber. I felt bad for all the drivers that lost their jobs.
They are still losing billions a year.
