37,000 + with life still there is pretty good IMO.
Moving to the hills, curves and mountains from a flatlander state, I really seen differences for mpg brakes and tire wear.
Consider vehicle weight as an issue too. Our SUV might be around 4300# so it seems if the brake pads/rotors hardware were apples to apples, as my 3200# car with lighter wheels and tires, that would seem to play a major role as well. Our Mazda is just under 30,000 mi with oem brakes still. I gave the orig tires the boot just recently.
Front rotors and pads went fast on a 22,000 mile early 2000's Ford Focus. I was told the car mfg's were cutting corners on cost and weight for EPA figures so things were a bit under sized or thin. True or not, it had the intended effect. Great mpg at the cost brake jobs / parts about 30% more often than might be the 'norm'.
I'm not cheap per se but mindful and my driving is usually smooth and undramatic which nets decent mileage and does little to stress or heat up the brakes. I'll usually pump them a bit early on so I'm not rushing to the light or as a hard stop.
As many said, driving style and habits play factor too.
