All of this sounds like normal driving behavior to me? I see it every time I commute to work. I think if you want a driver who doesn't do this you'd need a real commercially registered driver with specific training.
It is, but it shouldn't be. We don't pay all of the other drivers on the road, but we do pay for the uber we're in. I don't think it's unreasonable to expect someone performing a commercial driving act to need to do so safely and correctly.
