Why does people think driving is less than racing ? All racing games are driving games, when you are racing, you must be driving the car. When you drive, you may not be racing, you maybe cruising on a sunday drive, rallying ( off roading ), or even drifting for style.
When we control the car, we essentially driving the car, no matter at which speed/pace, grip or sideways, off road or not. When we drive against time or other car to reach certain goal ( time or finish line ), then we are racing.
It is still driving, the fundamental part of car, GT as the real driving simulator fits pretty well. We can call GT5 a racing game or driving game, both are true.
GT6 is now online car life simulator, that's even more than driving simulator, now we have car life
Time trial is a race, it's you against time, just like when I want to get to somewhere in time, I raced to get there, drove like my life is within inches of death
