Well, unfortunately about 70% of the replays of the top 10 guys I've watched are not that impressive, rather than just abusing some "glitch" of this type - either going too wide of a certain corner in order to get greater exit speed or running through chicanes' grass without getting any penalty. Don't get me wrong - there are plenty of really fast guys who play by the rules and it is a real joy to watch their replays and how smooth they are - but for the first type of "fast" guys - well, PD has to take care of those glitches ASAP.
