Dude, I've pressed you hard down the Mulsanne in a 787B. Your car was all over the place. I assumed it was because I have 5G internet, not fiber, and... key point here... stayed just far away from you to avoid a crash no matter where your car jumped to. Is that why you won? I don't know. My response to losing that race was the exact same as getting jacked on the Sardegna CE: practice and get better. I had some of my best racing following both events, including sitting on the poke at Le Mans and four nice gold trophies where it says "Sardegna Road Track A Circuit Experience."
Lag and cheating are a part of online gaming, and YOUR response is NOT someone else's fault! Report it and move on. If the problem persists, run different races, play at different times, run some single player for a couple weeks, etc.
You wouldn't drive your real life car in a way that something beyond your control, however unlikely it is, would cause a crash, would you? If the guy in front of you is drunk or driving dangerously, do you rush to pass him? If someone behind you is driving aggressively wouldn't you turn off to get away from them, or would you just let them ram you? Do you even look behind you when you drive??
Lag works the same way, and you must factor it into any online game. If you don't, YOU are at fault for the results. If that makes you angry, YOU are responsible for controlling that. If you don't like GT7, then you shouldn't play it. Maybe Stray is more to your liking?
Who changed the CE times? PD did.
Who got on here and complained about it? I did.
Who made a fool of me over it? I did.
Who actually did something and re ran the CE to 0.1 seconds of their original time? I did.
How many of those can the developers control? One for sure, but I can find a hundred ways of making myself look ridiculous online. Griping about in game lag falls second only to driving a pink and hot green 787B with Elmo and Miss Piggy on the front.
EDIT: I do agree on the radar for two reasons. #A, find me a radar in a stock Sambabus or a stock Raptor. I'll wait. #2, that MFD is also used to check weather and change fuel maps. #D, the entire MFD can be shut off to make the game more difficult, thus forcing you to hone your mirror/turn your head and physically look skills.
