I agree with all of your observations.
I believe that the tipping option is more visible and accessible in the Lyft App vs Uber App, hence the increased rate of tipping.
The ratings are lower because they were rated low when they were using Uber.
I just noticed something!
The pavement where the sign is lowered and it is across a driveway.
Apparently it is lowered to give access to the driveway on the other side and the no u turn sign is there to disallow u turns from that location, not the intersection 200 meters away.
And that’s why...
You can go past it if you exit a plaza on the road instead of entering the road from the previous intersection plus when you get to the left lane a bit late as you let the police cruiser get past you -or your ass if you wish to put it so.
I got a ticket for disobeying no u-turn sign
In my defence the no u turn sign was 4 poles behind the intersection and there were no no u turn signs were present at the intersection (ie: not in the lamp posts nor traffic lights next to me and neither at the ones across).
I had exited...
