Disc brakes
It's my turn to ask a question that relates to gas mileage (timely subject).
Why on earth were disc brakes designed the way they were where the pads lean against the rotor? Every vehicle I've owned with disc brakes had so much drag when you spun the wheel, you couldn't even get one full rotation.
You young bucks......when you spun a wheel with brake shoes, you had to wait forever for the wheel to stop spinning!

A perfect disk brake system should not cause significant drag. However, if the rotor is even slightly warped and/or the caliper is not aligned properly or the puck(s) do not return freely, the wheel will drag.
Drum brakes actually have more pad contact on the interior of the drum than disk pads on a rotor. When drum brake pads do not back off completely and/or when they are new, drag may occur.
Still, the most appealing things about my Dad's new two-tone green, two-door hardtop, 1953 Studebaker were the drum brakes.
When Nascar and Formula Racing retrofit with drum brakes, I may or may not follow suit.
