It's been a rough couple of days for Muni, it appears! On Friday, a bus driver drove straight into a parked fire truck, and on Sunday afternoon, service across the entire Muni Metro system was brought down by an errant computer.

The bus collision is a curious one: As reported by the Chron, the driver of an inbound 35 bus struck a parked fire truck at the intersection of Diamond and Wilder Streets.

A passenger says that “The bus driver just said, ‘It’s not stopping! It’s not stopping! And she was visibly pumping her foot on the brake.”

However, a Muni spokesperson says that "the driver told investigators at the scene that she did not believe the brakes had failed," so it's unclear why the bus sailed through the intersection and into the San Francisco Fire Department truck.

There were no significant injuries in the collision, the Chron reports, and the SFFD truck sustained only minor damage. On the bus's end, it appears the bike rack was the main casualty in the crash, as the vehicle itself wasn't crunched in the collision. It's still been removed from circulation, Muni says, so investigators can figure out what went wrong.

Then on Sunday, Muni was hit with another issue when a reported "computer glitch" brought down its entire light rail system.

As noted by the Ex, at 3:56 p.m. Sunday riders were urged by Muni to use surface buses instead of Muni Metro, due to a "computer problem."

About half an hour later (long enough, perhaps, to turn it off and then on again?), Muni tweeted that the Metro was back in business.

As you can imagine, many riders were peeved at the delay.

Sorry, Mr. PerLee, it's not just your monthly pass that's going up: single fares (cash and digital) will also see increases next month. Enjoy!
