Maybe you have experienced sometimes that very fast cars like the P1 or Zonda R (or highly modified tuned cars) can climb too fast towards Flugplatz on Nordschleife (the jump section at the start of the Ring) flying off track into the barriers or onto the grass.
This ai_hint tiny mod lets the AI cars slow down to 200-240kmh max just before the lift off section, preserving a guarantee safe corner exit and keeping a fair amount of corner speed.
It is also standard protocol now in real life since the unfortunate death of a spectator at a GT3 edurance event where a Nissan GT-R GT3 lifted off over the barriers into the crowd.
Test for yourselves (no vid, sorry) don't forget to backup first ;-)
Just overwrite in ks_nordschleife tracks.
