People who try to bring race cars into street car races are annoying.
Exactly that ^^^
It's not that people hate race cars. It's that people like to race road cars too... and they want to make it clear that's what they're doing in there, and race cars are not welcome.
It's hard for sensible adult newbies to be prepared for the ridiculous things that go on in some of the pub lobbies...
Like jokers who try to bring race cars in to "cheat" against road cars, and get easy wins.
Of course that wouldn't make sense to a rational adult. But just remember you don't know who's in a pub lobby... Kids play this game too. Don't you doubt it.
The player could be 8 years old, and just not understand it doesn't make sense.
They see a race... and hey, to a little kid, why would he bring anything BUT his fastest car to a race? In a little kid's mind, anything else wouldn't make sense.
Kids don't understand nuances. It probably takes a certain level of maturity & chronological age to understand the concept of "making a challenge for oneself". That's why kids games are often far more structured than games for adults. They need guidance and clear objectives, and distinct game provided challenge.
And sometimes the only thing the kids understand is a big fat "NO RACE CARS" sign.
They can't be reasoned with. They just have to be told NO, and then kicked (out of the lobby) if they don't listen up.
Then there's the teen population. Now, I'm not saying all teenagers are the same, or very silly. Because I know that's not true. Many teens enjoy the game in the same way that many adults do. But they do have a scientifically proven tendency toward shorter attention spans and pronounced mood swings. It's completely natural.
Like you could be in a room with them and hear that they're teenagers on the mics, because their voice tone is somewhere between boy-to-man. And one minute you could be in a clean shuffle race room that's actually great fun... I don't mind playing with kids if they're playing the way I like to play.
But one minute it could be a clean shuffle race... And then the hormonal emotional tide swings and BOOM, on goes the boost on HIGH, and the mayhem begins. LOL
Of course there also could be the "gamer" goofball types, or maybe there's also just mentally unbalanced people who think it's fun to win even if they're cheating in an obvious & outlandish fashion.
But I think most of the time, the griefers are simply unsupervised little kids who just don't understand, and just don't know any better.
