I have lots of street miles on bronze gears. I have worn some out but never destroyed one. I always try to run as thin of an oil as I can and still have good idle oil pressure and I know that helps keep the load off of the gear. My current motor will hot idle at 25-30PSI on 5W30 and runs down the road at 60PSI.

I think the gear in my car has 2-3 drag weeks on it combined with any other street driving I do. I haven't inspected it since 2019 but will probably do so before drag week this year.
