@drgeraint @bikenite A3. There are lots 馃槥 There's a section of Webster St. in Downtown Oakland that has painted bike lanes. But drivers park in the bike lanes all the time so they are not usable. https://www.google.com/maps/place/Webster+St,+California/@37.8116214,-122.2661635,17z/data=!4m6!3m5!1s0x808f8753a909af45:0xaa4485d05257ade2!8m2!3d37.8139354!4d-122.264758!16s%2Fg%2F1tt0rc2t!5m1!1e3
There are other terrible roads where it is scary to ride on because there is no dedicated space for cycling and because drivers go very fast.
There are very nice new lanes in Berkeley by the University that have concrete protection and are nice and wide for riding together. https://youtube.com/shorts/Tssmr0tElOw
