Cars - what is the point of having Rev counts on display?

RE: My dad said to me once, its a good gauge if your engine needs tuning,

They are about as handy as toothache, very little use unless possibly you were mutton geoff, I've driven for 20+yrs, cars, hgv etc and I never take any notice of them, I hardly look at my speedo never mind the rev counter..
I think people associate them with sporty cars so maybe they help to sell to boy racer types, they are a pile of /poo

do you not use your speedo to check your speed? (doh)

 

They're just tossers

And I bet there's don't go upto 18,000rpm (neer)

 

At 5,000rpm on the Civic Type R and 7,500 on the VFR800 if I remember correctly!
