The only solution is to ban all auto traffic and only allow busses in concrete separated lanes.
Most of my experiences driving it are late at night, after last-call, sharing the road with intoxicated tourists, it was total insanity. Between the copious amounts of confusing signage, partial lane divisions, crazy painted lane colors, taxis/ride shares obstructing the right lanes compelling drivers to use the bus/taxi/carpool lane to get around them... oh man.
I remember one night mowing down the flexible plastic divider posts in protest, at about 2MPH. Thud, Thud, Thud, Thud, nobody even seemed to notice, well, other than my passenger. It's such a circus.
No cyclists were threatened or harmed, there was nobody at risk. Bollards won't stop an inattentive driver from hitting anything, as evidenced by my trivial rolling over them without even scratching my car's bumper.

I'm referring to the plastic tubes on flexible bases that spring right back up when driven over, at low speed it's as if nothing happened. This was ~8 years ago, maybe Market is different today.
They were definitely standing afterwards like nothing happened, it's not like I rolled on them with my tires crushing them like the UPS guys do.
Uber and Lyft refuse to route their rutabaga drivers down Market, so I always try to catch a cab because it cuts 5-10 minutes off the journey.
