Its been said by others, but the aspect of Oakland and the greater Bay Area (and maybe this is just the most visible) utilizing new technology the most is in transportation. Whether this is the Golden Gate Bridge going cashless and snapping photos of drivers license plates to mail them a bill, signs in bus shelters showing bus arrival times, cameras that catch people running red lights, or using NFC to pay for your BART tickets, transportation and traffic enforcement seem to get the bulk of investments in technological innovation.
