There are a few issues I have had with BRR. First, it seems I am racing against cars that didn't run the same race with the same traffic as me. I say this because I have seen my opponents on a few occasions drift THROUGH a car and it not slow them down. That tells me that car wasn't there when they did the run.
Second, there are some races where hitting the ramp actually crashes you into overpasses and yet my opponent flies under me and keeps going. And this isn't times where I hit the ramp off the side and it launches you - I am hitting is flush and straight and it crashes me into an overpass, then I slowly float to the ground.
I am also amazed at how I can race with my 995 La Ferrari and get perfect launches most the time, but on BRR I get lots of lag in the countdown and rarely get a perfect launch.
It's to the point that I may just bid adieu. I have been playing since October 2015 and the gimmicks they keep coming up with are getting old.
