With the hotheads who'll wait a whole lap to try and block you, hit the pause button just before you reach them. It is
sooo funny ghosting through them, unpausing and then carrying on. It gets a rage quit every time out of them with all the time they're wasting. Your lap's gone, but man, it's funny. I imagine hearing a "huh?!!" every time I do it.
Brake checkers are good to bait as well but you have to keep a couple of car lengths behind (slow to their speed if you have to) and show you're trusting them. Quick reactions needed but if you time it right, they're at least a couple of seconds behind
you. Cussing loudly as they try to make the ground back up probably. Be warned though, the stubborn buggers will go out of their way to keep trying till they manage to get one so I wouldn't do it too often. At least you'll know who to look for and can plan ahead. Don't risk it in the turns though. Only the straight sections.
If you're getting frustrated with QM's through the daft drivers, look at it like I do and relate it to poker. You'll always get the occasional bad beat in poker but you'll always be in the next hand with QM and have more cards to play with what you've learned.
As a rule, I never go for the win in my first race on joining quick match. Even if I'm room swapping and already warmed up. I hit pause on the grid, let everyone go then start my race and see how people react when I'm attempting to overtake. If they're struggling, I give them a nice wide berth. If they're blocking and weaving, use it to set up a pass as they're sacrificing their line to do it. Brake checkers are a short, sharp shock to you so always be prepared for them but they only have to do it once for you to know what they'll resort to.
Lastly, never retaliate. However tempting it is. Why risk a penalty if you can do it cleanly? You'll likely never see another clean race with that person in the room and there's a good chance you'll draw other drivers in after they see what you're doing. There's also a very good chance you'll see them in the following days in other races as well and memories are long in quick match. Very long.
Build up a reputation of being a clean and courteous driver. We all make mistakes every now and again so if you know you're at fault for a move, say sorry and diffuse any trouble before it starts. Say nothing and it looks like you did it deliberately and can expect the same treatment back.
I was racing against
@coryclifford (he was undercover...) last night, lost a bit of control on the turn (Cape Ring) before the last hairpin and accidentally (honest!) hit him as he turned in. He got the penalty but as it was my all my fault, I waited and gave the place back. A bit of me wishes I hadn't. His elbows stick out further than most when you're trying to overtake but I know I did the right thing. I said sorry and admitted it was my fault. Rinse and repeat a few hundred times and it's amazing how much trust the other regular QM drivers show you.
I felt just the same as you when I started doing QMs. Not anymore though. I love them.
Long story short, don't get mad and don't get even. Just enjoy your racing and keep trying to improve.👍
