There is a such thing as excessive logging. Often it can actually cause you to miss important events in the noise. Just imagine:
Cylinder 1 fired, Exhaust valve 2 opened, intake valve4 opened, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, ad nausium, engine on fire, blah, blah, blah, shutup compression filter,blah, blah, blah, blah, blah blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, relax will ya? blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, get over it, blah, blah, stupid filters are stupid, blah, blah, blah, blah, blah, blah, blah, blah, blah,, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah, blah.
Yes, excessive logging can be a problem to the person searching through it, but not really for the system itself. Yes, there are cases where it will negatively impact performance, but I am pretty sure it is not the case on any default Windows installation being put in use for typical use-cases.
A car sending chatter like you mentioned on a debug bus wouldn't be a problem (and it isn't) because debug hardware is only used by experienced persons with adequate understanding to apply filters on the logging being broadcast.
So, I still am not convinced that "excessive" logging is a bad idea. It certainly is much less worse than not logging enough, in which case information *is* lost forever.
