If we're required to vote based on the image of the people who drive these cars, it should be the "Seriously Uncool Wall" because all of the stereotypes are uncool.
Straight line muscle-oriented cars are for "GRRGH TORQUE" meatheads. Lightweight roadsters are for haughty holier-than-thou enthusiasts. Supercars are for spoiled rich showoffs. Fuel-efficient cars, electrics, and hybrids are for haughty holier-than-thou greenies. Sporty AWD cars are for Ken Block kiddos and wannabe rally drivers. Anything cheap and remotely sporty is for high school kids, ricers, stoplight drag racers. Luxury cars are for pompous assholes. Old quirky cars are for hipsters. Minivans and crossovers are for soccer moms. Trucks are for compensating men. Off-roaders are mall-crawlers. Bland commuter cars are for the elderly. Nothing is immune. If you apply any of this to some cars and not others, you're being selective.
I vote based on what I think is cool. Sometimes it aligns with what I like. Sometimes it doesn't. But it's based on the metal, plastic, and rubber bits, and its history or the efforts that went into it. Not the meatbags you might see behind the wheel, depending on where you are.
If the ultimate intention of the GTPlanet Cool Wall is to reflect an "objective", formulaic common viewpoint of cool based on how the general public considers things, it should be a panel of judges rather than an open vote. Then those few could make all the lame predictable judgment calls, like how I knew "douchebag" would be the word of the day before I even opened this thread.
