Of course it does. When I stopped using my car for a taxi I would commute 25 miles each way, of which a good 20 miles was a continuous drive with no need to brake. So 40 miles a day where I barely touched the brake pedal. Now I remember driving in the taxi job in a busy town with small, short UK streets where I'd be on and off and on and off the brakes all the time. That is nothing to do with not looking ahead. You've seen the pictures of UK streets above and even taking it easy you can't help people walking out in front of you or cars stopping suddenly. In one mile I could have used the brakes 30 or 40 times. Times that by 100-130 miles a day or more and I've used the brakes a lot. Compare that to the commute use I refered to earlier where I'd barely use them in 40 miles and you can see how I wore mine out in 30k miles. Simple. And the dealers weren't replacing them before they were due. I had them changed when they were down to 1mm which is a requirement of the taxi licence. The Prius was better than other automatic cars used as a taxi in my town where you'd be lucky to get 15k miles out of a set of pads.
