By 7-1 vote, BART Board of Directors approved the Oakland Airport connector:
The BART board voted to award $440 million in contracts for the construction, operation and maintenance of the 3.2-mile Oakland Airport Connector. Construction of the automated, driverless train system that would whisk passengers to the airport in 14 1/2 minutes is scheduled to start next summer and take 3 1/2 years.
14.5 minutes to travel 3.2 miles == 13.2 miles per hour
This, for a line with no intermediate stops. Bicycling would be faster!
