We noted several weeks ago the city’s ambitious new plan to dedicate whole lanes of traffic to ultrafast buses with their own curbside turnstiles. And how would these buses battle unauthorized motorists slipping in and out of the lanes? By snapping pictures of them and ratting them out to the city. Nice. But not nearly as effective as a high-tech — yet awesomely brutal — solution implemented in Great Britain. Marvel at cars getting mauled by weight-sensing, automated retractable bollards.
