So you choose to wear your brakes out and waste fuel when you could
simply select a lower gear? How odd.

When you are going downhill and so have your foot off the accelerator, how
will using a higher gear consume more fuel than doing so in a lower gear?
Surely in a modern car with an engine management unit the fuel consumption
with your foot off the throttle and the car in gear rather than in neutral
will be zero because the EMU cuts off the fuel supply.
But I agree with your point about increased wear and heating on brakes.

If you were a Police Advanced Driver as you say, you'd know the accepted
opinion on the use of engine braking. There may be some differences of
opinion of the extent to which it is used with regards to manual
selection of gears in an automatic, but not that it shouldn't, as it
appears you're trying to say.
