Good observation tpl! In any event, it's a scary article. The only real effective way to address the problem of aggressive/illegal/sloppy/distracted driving is for cities to contract a fleet of unmarked vehicles (no, not Dodge Magnums, I'm talking 1998 Corollas) with trained individuals having "special constable" status. Drivers would have absolutely no idea which cars around them could potentially stop them and issues ticket(s). Focus would be upon offenses not normally covered by police. For example, cell phone usage, not stopping on right turn on red light, tailgating, dangerous driving, speeding in parking lots, driving too slow, etc. Lives would be saved and driving would eventually become a more pleasant experience for all.
