What has happened to the bus system in San Francisco these last few days!? Ever since they cut back the line frequency on September 24, the whole system has been total chaos. I don't understand how they have the funds to install the "next bus" system but not enough budget to get me to work on time. "Next bus" is worthless when the next bus is coming a half hour from now and in a useless pack of three. I sincerely hope they get this straightened out soon.
