Suspect not many non petrolheads have ever seen 4k revs, never mind 7k 
Probably not, it could be that with the popularity of diesels, which typically don't rev much above 4.5k anyway the general public don't see the point of going above 3-3.5kJagXJR said:
Do the latest DPF diesel cars not reinforce the message that you have to drive a car hard sometimes just to clear it out and keep it running smoothly? That revving a car is actually good for it (in moderation)?
Not sure about diesels but while researching RS4s I was very pleased to find that you have to drive them like you stole them on a regular basis or they need decoking at a cheeky £400!
It's sad that it's true. trashbat said:

I can't see why an Italian tuneup would resolve the problems of direct injection.Owners forums seemed to claim that RS4s mostly in cities with stop-start low-rev driving suffered worse.
I am very prepared to have said a stupid non-petrolhead thing!!

I have a similarly problematic, but much less exciting, direct injection engine. The problem is essentially coking up of the inlet due to no cleaning effect from fuel wash, so vague ideas of a self-cleaning oven aside, there is little to be done by the owner. Driving style might serve as partial prevention, but not cure. The remedy varies from slightly intrusive (e.g. walnut blasting) to full dismantling.Owners forums seemed to claim that RS4s mostly in cities with stop-start low-rev driving suffered worse.

I imagine a quick blast to the walnuts would be more than slightly intrusive!walm said:

I told him I'd have a look at it - we replaced the air and oil filters, gave it some Super Unleaded, a double shot of redex, then I took it for a drive. He went bats
t at how much I was revving it (once warm, almost redlining every gear) as it was chucking out a fkton of black smoke.Once it stopped making the smoke during gearshifts, we took it back to the MOT station, and it passed quite comfortably.
When it came time to sell (he needed something smaller, but with ISOfix) I advised him to get a Golf diesel. He's had it about 5 years now, and loves it.

I don't doubt it works on some engines in some contexts - but the RS4's problem is specifically to do with direct injection.I told him I'd have a look at it - we replaced the air and oil filters, gave it some Super Unleaded, a double shot of redex, then I took it for a drive. He went bats

Friend at work talking about his new (to him, '07) BMW 116d, comparing it to my EP3 Type-R: "Yeah, mine's faster as the redline is at lower rpm so I get to my powerband quicker"
I'm glad I'm not the only one who wants to hurt people who continually say "doesn't matter how fast it goes, you'll get there at the same time as the rest of us"

Challenge them to a race from one end of the country to the other. Make it a requirement not to exceed the posted limits. A faster car will still win by quite a margin, or at least that's what I would expect from my experience of reasonably long journeys. The scale of the difference depends on the type of roads, but it can be as much as 10 mins per hour between a slow and a fast car (more overtakes, less acceleration time, easier to maintain speed on inclines etc).I'm glad I'm not the only one who wants to hurt people who continually say "doesn't matter how fast it goes, you'll get there at the same time as the rest of us"
In any case, the kind of people who say that drive at 40mph in 5th everywhere except on the motorway. One of my brothers (to shame) never goes above about 3000rpm as describes 45mph as a 'good speed' for NSL country roads. He takes ages to get anywhere!

Certainly no myth. RS4's will develop this problem over time. As far as I know its only the 4.2 FSI engine and doesn't appear in the 40v design in the S4 Owners forums seemed to claim that RS4s mostly in cities with stop-start low-rev driving suffered worse.

Question to "Honest John" in this weekend's Telegraph motoring.
"Is my BMW X3 safe to drive in snow ?"
My answer...NO,stay at home if you're that useless.
HJ's answer was typically measured.winter tyres etc etc.
You could probably enter a question per week from HJ's column.
Sadly my torygraph reading father takes everything he says as gospel. Some of the advice is utterly shocking. "Is my BMW X3 safe to drive in snow ?"
