Students break the law and ride two to a bicycle. Passengers stand precariously with feet on either side of the rear axle with their hands on the driver's shoulders for balance. Perhaps based on their belief that they are bulletproof, these teenagers dart in and out of traffic. Illegal parking on these streets makes cars look like snow skiers as they slalom past the cars parked on both sides of the street. When you add to all these obstacles a good-sized truck negotiating one of these narrow arteries, you have a viewing experience.
Drivers begin the turn, back up, continue the turn, back up, and continue the turn again.
They watch closely as the truck's protruding side mirror edges nearer to the inconveniently placed concrete utility pole. If the driver thinks the mirror will only gently kiss the pole, he will inch the truck forward, slowing brushing the mirror against the pole. If he anticipates a less congenial encounter he will grab the mirror from the inside and pull it in. If all else fails, he gets out to push the mirror against the side of the truck. After clearing the intersection, he pulls the mirror back out.
