5,000 sensibly-driven street miles.
2 laps at Mid-Ohio.
Take your pick.
Is that a ceramic, carbon, semi metallic, organic pad? What kind of rotors? How heavy is the car?
A few months, and I'm being that vague because I don't know how you drive or what the brake bias of your car is. On my car, the way I drive, probably 2 months and there would be a paper-thin sheet of friction material left.
ceramic. Car weighs 3336. I now drive like a middle aged wage slave.
2-3 months. I'd change it before winter, though, you don't want your brakes to be iffy in inclement weather.
Are you kidding?
If brakes wore that fast [1mm per 1,000 "sensible" miles], they wouldn't last to 20k.
Even if you want to change them at 3mm [outer limit if what's recommended, depending who you ask] they would be completely worn to the backing at 30k, give or take a few.
As I already stated in the Jap section, you're probably just past 50% worn [new pads tend to be 10 -12mm]; if you drive easy [and highway miles as you stated] you should get at least 10k, probably closer to 15k or even beyond that, especially being ceramic.
However, if you want to push how far they'll SAFELY take you you NEED to pay attention to them.
If you hear squealing/grinding take them in to be checked.
Also, there's a lot more to brake replacement timing than just pad thickness. If your rotors are trashed; badly grooved, badly warped, worn too thin, rusty [lack of use tends to rust the inner surface] then you might want to think about replacement sooner, even if the pads have usable material.
My rear pads wear out every 20k or so.
