Grid is fantastic, but the way it puts ice under your wheels when your in the lead can be frustrating at times. Several times I've been finally leading a race by a good margin only to spin out unexplicably.
If I had a dollar for every time I've lost control and spun out in GRID, I'd be a rich man. Over time I've deduced that it has little to do with the game and more to do with me simply being bad at it.
For a long time, half of my spin-outs were a consequence of me constantly trying to use the handbrake to pull off drifts. Eventually I realized that GRID isn't an arcade game and you can't just pull of perfect drifts at the press of a button.
In fact, I learned that you really shouldn't be drifting much at all. As soon as I took the game more seriously and actually slowed down properly at corners, I instantly became more successful.
Yeah... that's what happens when you go from playing Trackmania over to playing GRID. :$
