I just watched two completely different people be complete morons in their cars, in the space of an hour, within four blocks of each other. The first one, someone driving a smaller sedan (mid-to-late 90's Corolla or similar) was turning left off of a 5 lane road (two lanes each direction plus one suicide lane) onto a two lane road (which at that point was barely three lanes only because they've squeezed a right turn lane in at the intersection). She had a green light, but not a protected green turn light (i.e. she needed to yield to oncoming traffic). The speed limit on the street she was turning off of is 35, and people have been known to push that up to 40 - 45, even though that spot is right in front of an elementary school (there's no school speed limit zone there because they built a pedestrian overpass or some such bullshit). Traffic in the uphill lane closest to her as she was headed down the hill was backed up from the intersection further uphill from the one she was turning at to beyond the intersection she was at. Traffic in the right-most uphill lane, was not. She attempted to turn anyway, and was hit by a small pickup (Chevy S10 or similar) hard enough to push her car out of the path of the lane that she was turning into and into the path of the left-most oncoming lane, where she hit the driver of the vehicle that was first in line at the red light head-on.
The second happened in our apartment complex "driveway." This is one of those driveways for apartment complexes that're more like two-lane roads with head-in parking on either side. This driver always, every single time they park their car, backs into an extremely clearly marked head-in only parking spot. We're talkin' they back in to the spot where the sign that says "head in parking only" is hanging. I've known this for months, but what I didn't know is that they apparently routinely pull into the driveway normally, driving mostly down the middle of the traffic path, pull up to the mail boxes, get their mail, and then back down the driveway (about 250 - 300 feet) weaving back and forth like drunks (I'm not ruling out the possibility that they may actually be drunk), until they get to a parking spot that's empty and then whip around (still backwards) into the parking spot "rubbing" the two cars on either side of the parking spot in the process. Rubbing in the Tom Cruise, Days of Thunder, rubbing is racing sense of the word. I don't think they've ever managed to dent anyone's car, but they've certainly managed to trade paint with a few, my wife's included on two separate occasions.
