This afternoon Aleksandr Milewski posted a picture that suggested the ticket-less streak might come to an end, but now Google says its car was flagged down because it was going so slowly. These new prototype models are classified as "Neighborhood Electric Vehicles" and have their speeds capped at 25mph, so they stick to slower-moving streets. The officer had some questions about the car, which is apparently common for the cartoony vehicles. According to Google, its self-driving vehicles have driven 1.2 million miles, or the equivalent of 90 years of experience for an average person -- and probably still can't get an insurance discount.
