We all have sampling bias since the number of rides we take is so small compared to the number of ride givers. I'm sure most taxi drivers and most Uber drivers are perfectly normal, safe drivers, with the outliers being the problem.

I've personally been driven by awful taxi and awful Uber drivers, though Uber so far has the distinction of being the only one to genuinely scare me driving 3x the speed he should have on a twisty road, with tires screeching the whole way.
