You would need to more carefully define "average driving conditions". Also
the driver is more of a factor than the conditions.

I have been driving for 43 years, at an average annual milage of around
15,000. The vehicles have been everything from old heaps to brand new. Some
of them I have kept for more than six years. I have *never* had to replace
the clutch in any of them.

OTOH, I know of drivers who regard the clutch as a wear item to be replaced
every couple of years. Just remember that it only wears at all when your
foot is on the pedal!

I put 250,000 kilometres (150,000 miles) on a clutch on a Plymouth Horizon.
Car went to the crusher with its original clutch. It saw a mix of country
and city driving, including commute road-warrior duty.

I'm an "easy" driver: acceleration matching the prevailing traffic,
slow steady use of the breaks. On my 1997 focus 5spd, I had 145,000
miles on the original clutch & breaks when I sold it.

So far that has been the most trouble free car I ever owned.

Now driving an 05 focus 5sp zx4.
