This way I both struggle myself (as I never want to go there that early) and harm the others' comfort and convenience by occupying the place, making the queue longer. People also tend to conflict, fighting for their place in the queue (I had to witness and to participate in too many queues in my life, people become nasty there).
If I know it's random I come whenever I'm comfortable.
Would you pay more to guarantee getting the highest rated driver near you?
I haven't had a "bad" experience, but I've had some better than others.
Part of Uber Comfort's value proposition is that only highly rated drivers are allowed to participate.

Meaning you still wait the same amount of time on average, just have a bunch of "that was quick" and "wtf. I'm waiting for 4 hours" thrown in there. Not an improvement if you ask me.
