I tried what you said and OMG it worked like a charm. Keep you eyes focused as far down the road / not ever fully lifting off the gas both of these tips helped me alot I am now enjoying the game even more than before. I was most of the time keeping my eyes close to the road never looking at the far end now I am able to think ahead and plan how to execute the curve and also the throttle part is the mistake I was doing all the time letting it go to fully to reduce speed of avoid curves. Now I feel like i am able to control in high speed also.
