In theory, larger brake rotors matched with larger area brake pads make for better stopping power and shorter stopping distances. If that is the case, then there appears to be a lot of vehicles with undersized brakes. I know there's got to be a logical engineering answer to this . . . what am I missing ??

You always want the smallest sized brakes that are just big enough to do the job. One of the things you can't see from the outside is the size of the caliper pistons as well.

Fixed calipers are great but really just money makers for street cars.

Honda was notorious in the late 90s early 2000s for having warped rotors. Every early honda that I owned did this. I did quit using the cheap tire shop and went to discount tire which helped as they use a torque wrench not an impact gun.
The pilot I drive occasionally is horrid. Brakes have like 4,000mls (dealership), and I can start feeling vibration at hard stops. I told FIL, don't do it in the dealership, and he did it.
Time to upgrade that stuff.
