Let's discuss a bit of this infamous technique. Check this out:

 
By skidding my way through both first and last turns at Spa, I have cut 0.956s off of a not too bad time, reaching a confortable place in Group B with a time of 1:33.591 in this Spa hotlap (not even fully upgraded or skillful at Monza w/ the Centenario).

And here is the last turn - or last tricky turn anyway. First picture is a gif image -->

Here you can see the tires direction in both turns, at the beginning of the... Mmmmm... To be precise, this is actually a skid but not drifting or powersliding stuff, since I'm not steering opposite to the turn or applying throttle at that moment.

What do do you guys think? Am I the only one here who uses this trick on purpose to gain some time?

Well, one thing I know: it is extremely fun and you should try it!!
