the idea makes sence though

they are the biggest company who ONLY make rubber belts for almost every car COMPANY aswell as to sell on after and other stuff that uses belts

it makes sence they use a design that aint affect by heat cycles/ different weather seasons/water and other things that will affect the lifetime of it inside the engine bay

if the cars dripping with oil then thats a different matter but they the spinning at 4 times a second would also act like a tumble dryer and throw it off the belt too before it soaked it aswell wouldnt it ?
