99% of driver know when to change gear by the sounds and feel of the engine.
I know no one who looks at a rev counters. Also this is distracting, taking
the drivers eyes from the road.


Actually, I found one use for it.

I was driving my old XJS up to workshire with my daer old whte haired
mum in teh passeneger seat.

She glanced across at teh rev counter and said 'are we doing 50 mph
dear?' as she looked at the tacho on the 5000 RPM mark.

I will leave you to work out what 5,000RPM in top gear on an XJS was, in
terms of road speed :-)
