Another 'traffic calming' measure found here in
Ottawa,
Canada is
zig-zagging
lane configurations, forcing drivers to
swerve left and right when entering or exiting
intersections. This becomes
dangerous when the
pavement is covered in snow. The
locals, used to the
funky arrangement, will swerve, much to the panic of
out-of-towners wondering why the
fsck is this guy is driving into his lane.
It should be noted that emergency vehicles are also affected by such measures, so in reality, someone somewhere may die because an ambulance could not reach him in time.
