Wish I saw this thread and was notified by Uber about SF problem spots, before getting this bus zone ticket.
I just read that there is plan to add rideshare zones, "Thanks to a $50,000 grant, Livable City —which is involved in policy, legislation and planning to create a safer, healthier and more accessible city—is aiming to "Curb the Cluster." The Just Transit SF grant, announced today, was administered by the 11th Hour Project, a program of the Schmidt Family Foundation. " (I can't post a link to that news article here until I get approved to post links, but I found it on hoodline, posted there in 2015/12 and planned to be available by Nov 2017?)
Does Uber provide a guide for SF drivers? Similar to the Up-Lyft guide? (Do a google search for 'caltrain' on 'uplyft-sf'.) They say in that guide, "San Francisco’s main CalTrain station is another example of drop-offs made difficult by Muni and taxicabs. You should never drop off passengers directly at the 4th Street entrance to the station…that entrance is lined by bus stops and frequently patrolled by parking control officers. There’s a side entrance on Townsend Street that works much better, but involved dropping off in a narrow (red curb) zone behind a bus stop and at the front of the taxi rank. Be prepared for some dirty looks, but I’ve never had a real problem dropping off at that location."
