I think the problem is that people get very used to driving passenger sedans which are usually very quiet and docile. They start to think that this is 'normal' type driving. \
When they get into a car with the engine directly behind them, and one that makes quiet a racket when it is operating in its version of 'normal', it leads them to think that they're 'over-doing it' or that they are inviting an engine problem by getting the revs up. For starters, while these aren't derived directly from race engine like on a GT3, they are still engineered to 'live' in the area of the rev counter that is nothing like that of a street car whose slush box is constantly short shifting.

It's somewhat counter-intuitive, a Boxster that is getting poor gas mileage (relative to an econo box) and making its passengers annoyed that driver can't ever hear them, is probably an engine that is running EXACTLY the way the engineers intended. And one reason why GT3 drivers always have a second car.
