Yeah that was the idea which Uber worked hard to promote. Then they started cutting rates...and they did it multiple times. Then they increased their base commission to drivers from 20% to 25%, as well as the introduction of the 'Safe Ride Fee' all of which goes to Uber (aka Uber's built-in "tip" for themselves on every fare)

Now the case in most Uber markets is that uberX drivers are working for half of what a local taxi would cost, in a cleaner / newer car (usually), and not getting any tips either.

The culture Uber started 4 years of 'there's no need to tip' sounded awesome all around but then drivers rates got cut more than half while the riders still believe there's no need to tip or that the tip is included.
