San Francisco Buses Slower than Any Peer City
San Francisco graded its transit service against a group of peer cities, and the results were...not great. While San Franciscans are more likely to ride transit than their counterparts in cities like Chicago or Denver, if they're on the bus, they are riding the slowest buses in the group. "Overall, a Muni bus averages just 8.2 miles per hour, the worst score in the grouping. Second-to-last-place Chicago beats Muni by more than a full mile at 9.3," Adam Brinklow writes for Curbed San Francisco.
San Francisco's buses are also the least reliable. The prevalence of mechanical issues on San Francisco buses is part of the reason these buses are so slow.
