You say you used to drive this every day.
1 - how did you measure these asserted traffic flows?
2 - over what period did you measure?
3 - how many cars ended up at LHR, where did the other cars continue on to?
I’ve worked at LHR for 20yrs, and I agree with Prophead. The majority of cars on the M25/M4 do not go to/from LHR.
