Behold my favorite #traffic calming device.
@TimWardCam @milgrim @cleatsandcode @davidho this is not true, because cars come in this street not perfectly aligned with its axis. It's wide enough for a normal car going straight, but the car needs to be perfectly aligned with the street prior to crossing the bollards, not worry about solving the alignment later.
(Correction: i see you mentionned that they have to be driving straight, but doing that immediately after a turn is the hard bit)
