From my experience, annoying, self-righteous soccer moms drive second-hand Land Rovers. What cars have annoying people driven in your experience?
German "premium" vehicles: Porsche Cayennes and Panameras... Mercs and BMWs... are usually driven by annoying, arrogant people here. Audis on the other hand aren't, because their owners can't even drive...
Peugeot drivers. Terrible on the road. Terrible off the road. Don't try and prove one wrong, for that would be a mistake
Wranglers (usually lifted with the doors off 90% of the time) Toyota FJ Cruiser Any Audi S or RS models Any lifted American pickup truck 2nd gen Chevrolet Equinox Porsche convertibles (I have good experience with non-convertible Porsche drivers)
On the East Coast, from worst to worst-but-not-worst-worst : NEW LAND ROVERS - Driven by "mommies", paid by "daddies", and completely unable to grasp the concept that there are, in fact, other people on the road. Will readily cut you off, flip the bird, and proceed to attempt to break the land-speed record on the Interchange (all while yelling on the phone) BMWs of any make - I don't even need to explain this one, I'd be preaching to the choir. Fullsize Pickup trucks raised at least 6 inches, with black-and-led taillights, and low-profile tires. Typically diesel but not always. Usually driven by a suburbs-yuppie-who-wants-to-be-a-"southern man" or a guy in his 40s who is desperately trying to feel young again but doesn't want to "risk" driving a motorcycle. Mercedes of any make from 2004 to 2014 - Driven either by yuppies, people of the "ghetto-fabulous" lifestyle, crotchety old men, or upper-class business people. All of these people will gladly "merge" in front of you at the last second because they. are. more. important. Audis of any make - Really just BMW drivers who are trying to avoid the stigma around driving BMWs Newer (2010+) VWs with aftermarket rims (I don't really understand the correlation here but...)
If you own a (new) jeep, you are probably in High School and have a 50/50 chance of being a girl... Little do parents know how fatal a small overlap crash can be in one of those things...
So basically anyone who drives a car is annoying? Judge someone for the way they drive not the car they drive.
