Let's look at Amado's comment that "sales dropped 80% after the bike lane was installed and created a hassle for musicians due to a lack of parking". Look at Street View, and you'll see every parking spot in front and around it's property is a parklet for themselves. Hmm, if they really needed parking so bad, why did they take it away from themselves? Same is true with Yasmin with their corner spot and their 4 parking spots converted to parklets. https://www.google.com/maps/place/Amado's/@37.7570262,-122.4...
The only thing I think could help the neighborhood more is if the city declared it an actual "Slow Street" because it is slow. You'll hit every red light and have to wait for pedestrians at every intersection. You have Ubers and doordashers and freight loaders blocking the road all day. Declaring a slow street would probably push Google Maps and friends to route users to Guerrero or South Van Ness which are 1-2 blocks away and are exclusively car friendly.
Why do I like this lane? Cars drive much slower because their lane is "narrower". It's still the standard car sized lane but they are now driving between a separated bike lane (bollards) and parked cars, rather than an unprotected painted bike lane where cars tend to just take over.
Moreover, it's pretty much the only north-south bike line in this part of town. West is too hilly, east is too car oriented.
Go to their website SF Small Business Coalition and their chief complaint is customers can't park in front of their businesses anymore. Really? This is one of the densest neighbhorhoods in SF and you're gonna complain about parking on the street? https://www.sfsbcoalition.org/save-valencia-merchants. you could build them a 6 story garage to store 400 cars and they'll complain about how it's destroying their community.
