The right speed everywhere is the key, whether braking , accelerating or coasting !!! How to judge whether or not you have the right speed is the problem here. Fast racers instinctively know how fast they need to be at each section of the track, but slower racers always think faster everywhere is the fastest way around and finding out they are wrong.... You will find top racers commenting more that their car is sometimes too fast, although it seems that they are going slow and can push it more... I say practice knowing the right speed, and forget about trying to blow by others in one section of the track to lose even more time in another section, and overheating tires in the process......
