Drift racing mode

[rookie1]

I've been think how to implement drift racing. My idea is to start simple. So as a start, we can add a drift score display in Practice Game mode. And award points depending on how long the player car stays in drift. The 1st question is, programmatically, how do we determine the car is drifting? Ideas anyone?

looks quite simple, compare the angle of the car and it's trajectory
that would be a bit "arcadish", it can't be compared with real championship of course, but why not
