No, not the failure to put qualified and experienced security guards on duty when expecting high-risk events. Everyone knows that staffing the late night shift New Year’s and the 4th of July with fresh rookies carrying live ammunition and sending them to deal with violent riders is a recipe for disaster. Oh, except BART who has made the same mistake again recently.

No, not the failure to keep the trains running. BART blames that on time. As if it is somehow not their fault to have decrepit cars and tracks after 40 years. They’re still trying to figure out the cost of upgrades by 2017 even though “they got a lot of cash in the bank” as it was said to me by the woman selling tickets.

No, not the failure to provide Internet service. They have tried to figure it out for a few stations but they’ll shut it down at the first sign of someone saying something they disagree with. They wouldn’t call that a failure and they argue there’s no cost to silencing passengers. Perhaps that explains why they also let the tracks squeal at over 100db (louder than a jackhammer).

No, BART finally has been forced by auditors to admit failure — $200K in customer billing errors:

Over 16,000 BART customers were overcharged for parking in the transit agency’s lots over the past two years, and now the vendor responsible for the mistake is to set to dole out more than $200,000 in repayments.

Due to a software glitch, motorists using the BART lots were incorrectly nailed with fees during the weekends and some holidays — times when parking is supposed to be free. The overbilling occurred during a 28-month period, and wasn’t detected until a BART customer complained to the agency, according to spokesman Jim Allison.
