So the yellow cab cabbies I see running Lyft + Uber while being horrible drivers must be the exception, right?<p>I feel like cabbie turnover is so high, if 1000 join Uber.. 200 get canned so switch to Lyft... 200 more cabbies will just join Uber the next month.<p>A rating system is good over the long term, but if people have an average life in a market of a few months - it doesn&#x27;t do a bunch.
