@CaltransD4 the new traffic light at El Camino Real and San Carlos Ave in San Carlos has weird staggered phasing that creates conflict between pedestrians and right turns from San Carlos onto ECR southbound. Please fix before somebody gets hurt!

Any driver behavior not prevented by a physical barrier is condoned? Clearly there needs to be a bollard to make it impossible for drivers to use the new 2-land cycle track on Gilman as a right turn lane. BPD nowhere to be seen, as usual.

We have been notified by @CaltransD4 that the Bay Bridge path connection to Treasure Island will unfortunately not be open overnight July 4th, and the path will close at 9pm. So biking to the island for fireworks will not be an option, unless you take Muni Line 25 back to SF.

Really only three factors we need for HOV lanes:
1. Restrict them to high-occupancy vehicles on 24-hour basis.
2. Ban solo drivers in cars of any type.
3. Retain exception for motorcyclists.
