We who live in the western half of SF are forced to rely heavily on Fell & Oak Streets. Any blockage on those streets is both inconvenient and a safety hazard.
It seems that at least half the times I'm on Fell at Divis., there is a backup of stopped cars in the left lane, waiting to pull into the Arco gas station here. This is inappropriate anywhere, and dangerous on such a major artery.
I see two possible solutions:
1) Require the Arco station to redesign its layout so cars can wait on premises, not on the public street;
2) eliminate 3-5 parking spaces on the left side just before this station, to accommodate waiting traffic.
Enforcement would probably help too.
