I follow but it doesn't make sense no.

If you are driving 8 miles twice a day every day this is plenty to get the car running at optimal temperatures.

you can't blow the soot through the filter by revving hard. it is specifically designed to capture the soot, to not let it through, if you thrash it you'll just generate more soot.

If all you used your car for was to go to the corner shop then that would be different. but you're not, your using it as intended, you don't need to do anything else.
With a Diesel car that only does short jouneys without going on the Motorway you need to occasionaly drive the car using slightley higher revs say using 3rd gear instead of 4th. Driving like this is about allowing the car to generate heat in the exhaust to allow the soot to be burnt off in the DPF. Sometimes if you are in traffic when the DPF regeneration is being carried out you can smell something is running very hot.
