rate of disk brake pad wear?

depends on how heavy your left foot is? do you double clutch,drive with right foot on the gas pedal and the left foot on the brake pedal? lots of stop and go driving? it will vary from car to car,person to person. i just replaced mine a couple months ago,they have been on there 10 years,but i drive mostly straight roads,not many curves(less braking) let my foot off of gas pedal if i think a stop light is going to stop me so i don't have to stop(more braking if i didn't)etc...

I don't think I've ever seen someone double clutch a Prius.
