Today there was an incident with the 24. Apparently a garbage truck was double parked and when the giant electric bus tried to go around it, the bus came off the overhead cables. Long story short, the bus couldn't get reconnected, so there was no power so the driver put the block under the wheel- off-boarded everyone and sat back to wait for help. Well, while waiting for help the bus lost it's block and slid down the very steep hill. I've ridden the bus up and down those hills- they scare me when the power is on. 8 cars and an apartment building where hit. MUNI service was only "slightly" delayed. And I have to say it all just makes me love the SF even more.
