Yes it is. If a car is travelling faster than another car, the slower car can't gain the time unless it gains enough speed to overtake the gap. The ricers beat other cars because the turbo kicks in later down the lane. That's the difference between two cars, not the same car. I feel dumber for even trying to explain this. Perhaps you should open a geometry textbook?
Two cars leave the line at the same time, one accelerates to 100mph, the other to 88 mph. Unless the latter is a DeLorean, is it possible to overtake the former? NO!
