I try to remember them all. I even catagorize them, but I get bored while driving. The saddest part is the number of new GT Mustang Sloths I encounter by far outnumbers the PT Sloths. Camrys are up there, but Civics & Corollas are not. Surprisingly almost every Corvette I get behind is AZ plated and SuperSlothing. I've recently seen a good number of Deloreans even, and they never seem to sloth around long.
LLBS: Older Caddys, PT's (all models), Toyotas (all models), Corvettes, BMWs, Mercedes, Yellow Cab (that brand, specifically), and all types of limos-private drivers. Rarely Porsches, Saleens, clbuttic cars, old VW Bugs. See also: SUV or motorcycle (w-Leather).
Stop sign runners: Minivans, SUVs, and older Subaru wagons, but I live near a pre-K. Also BMW 5+ series', electric golf carts, bicycles, and Buicks, plus people who would never be carded for an AARP discount (see also Buicks), and FedEx-UPS drivers.
Fart-can exhausters: Almost always Civic, Accord, Camry, or Mustang. If not, see also WRX and-or chrome.
Ignorant left turners: Trucks (pick up or larger), Caddys, Buicks, anything else senior ciitzens regularly drive, Neons, Cavaliers, 1994-2003 Mustangs driven by large ladies.
High beam drivers: Females ages 16-120, rednecks, illegal immigrants, people who's BAC exceeds their IQ, see also: AARP.
