Why are air suspension systems in busses and trucks way more reliable than any car?
I know they're engineered to last longer than cars generally, but they have such insane loads and forces, you'd think they'd maybe last about just as long? But I've run into several busses with hundreds of thousands of miles still on the original bags (some many years old), yet not a single car or SUV OEM can get air springs right for cars? Even Lexus will get leaking air springs relatively shortly into their lives. Feels unheard of for any passenger vehicle with over 100k miles to still be on the original bags, and the general attitude of repairing or rebuilding them is not a matter of "if" but "when". You'd think that with the lower pressures and loads they'd last longer if anything.
