I don't think it's necessarily jealousy.
This reminds me of the show "Mystery Science Theater 3000", in which a guy and his two robots are exiled to watch (and make fun of) cheesy movies. Fans write in all the time with suggestions of movies the MST3K crew should parody. The show writers comment, not every bad movie warrants MST3K consideration. For a movie to make it on the show, it can't just be bad, it has to be a certain type of bad- namely, the movie in question makes a
serious attempt to be something it
isn't, and whatever that attempt is, flops miserably.
I admit, when I roll up (in my volvo station wagon) to guys on sport bikes with extended rear trailing arms, trucks with double stacks/ coal rollers/"cummin's" diesel stickers and such, I will sometimes troll them into a "mock" race just for if the conditions are right. Like MST3K, it can't just be a bad bike, car, truck. It has to be a vehicle and a driver acting in a way that parodies himself in some way (for example a ricer weaving it through traffic, flooring it, only to have body unsecured fiberglass body panels flailing about be cut at the next red light, and making NO progress in any fast and furious attempt). It can't just be a parody either, it has be an almost comedic parody. And it can't just be a loud exhaust, or someone blipping the throttle because the engine is so poorly tuned it will cut off if they don't do so. Around here, that could be a guy trying to get into work and that's the best car he can afford. It has to be a pretentious, unnecessary
something. Like the TV show, the person really needs to be implying they are trying to be something they aren't. If blipping the mighty volvo throttle spurs them into hitting theirs, or worse yet, beat them (all in a safe under 25mph way...), it's all in good fun.
When I'm in the 911, I don't race. The car is what it is, and I've got nothing to prove. Ironically, I rarely get challenges either. Most people are thumbs up/ complements. The red color of a previous 944 I drove was an exception. It was showy, and I think it perhaps inadvertently contributed to the "parody" situation that MST3K alludes to. Also, my fathers plate "por5che" didn't help either! When I got a Black 944 with non descript tags, all the catcalling/ racing/etc stopped. People just ignored it, or gave thumbs up.
