IDK, I don't notice many. But I'm a very defencive driver who thinks for everyone on the road, not just myself. May be that's why I rarely get into those situations.
I don't drive those hours on Saturday usually, but otherwise I'm consistent within about $27-35 hourly after Uber's cut, meaning my actual earnings are within $20-25 after all expenses. That's doing X, XL and SELECT.
That's pretty good for UberX.
