I was quite startled the other day to see a motor vehicle take the path shown (below) along the bike lane on Point Grey Road just west of Macdonald Street.
The vehicle travelled the full length of the bike lane, and then proceeded west on PGR. This in defiance of the sign reading “no entry except bicycles”.
This behaviour is enabled by the driveway curb cutouts required at a few places along the bike lane, and by the width of the lane — particularly at the western end (second photo). The lane there has a concrete island, but the opening is still wide enough for a motor vehicle to pass through.
