maybe i'm completely off base here (wouldn't be the first time) but i don't see it as a distraction ...
i can feel the engine rpm's, it certainly would be a mix of engine noise and music at high rpms, but i "know" what rpm i'm at, i ran without a tach for the longest time, no problems shifting at the right point, never have to look at the tach anyways.
not just the sound, more like the vibrations. can't explain it, i just know where the engine is at.
no need to "sync" the music with the engine or something like that, i just think a good, agressive tune would push me a bit harder while i'm driving on the edge.
none of this is completely new to me. i've been on the track before, with fairly good results i might add.
i don't have to concentrate on driving much, stuff just "happens". i don't have to think about it.
i don't know, i barely even hold on to the steering wheel, i usally just let the car do the driving ...
(instructors worst nightmare as i let go of the steering wheel completely after a tight corner and let it straight itself out, always gets their attention!
)
but i'm certainly no "walter röhrl" or "mario andretti" (and never will be) ...
guess i'm just nuts!
