Doing it in standard or Professional mode is irrelevant for an addicted hotlapper, because hotlappers enjoy it any way they can.
This addiction is about continually shaving time off your personal best, and physics dont even come into it. For me it all started with Mario Kart many many moons ago and it has progressed from there. With the release of GT1 and the increased popularity of the Internet, it became possible and essential to hunt down better lap times to chase and to post your PBs for all to see and chase.
There was another addiction that was equal to hotlapping back then, it was called Gold Junkies.
Gold Junkies werent only content in just getting gold license times, they were obsessed with shaving as much time off a gold time a possible to satisfy their addiction.
Here is a famous but now rarely used Gold Junkies quote that also highlights the symptoms of an addicted hotlapper.
I am honoured to quote this after so long (1999 / 2000?):
You've been warned.
