Show me one car that has diagonally opposite hydraulic brakes. I dare you.
They're all split front/rear because the different axles provide different braking power. Most of the braking happens in the front; rear is primarily for stability. When you press the pedal, in fact, the rear brakes engage slightly before the front in order to add stability while braking.
Don't get sassy with me son, I'll put you right where you belong.
That's great but technically: Not a car.
Are we going to Mrs Cumberdale's?
Buuurrrn
Here’s an entire manufacturer: Seat
Interesting, I was unaware of that one.
I'll look more into it later, learn about its failure modes and whatnot, but off the top of my head, it seems like it would still be a less effective system. I think I would much rather have one axle working. That mitigates the case where the two wheels are on different frictional surfaces, which could leave you with just a single wheel braking.
And still, if the fluid reservoir is a single undivided container, I'm not able to imagine a case where two wheels - horizontal or diagonal - would fail at once.
Examples and Explanation of Diagonally Split Dual Hydraulic Braking Systems
Diagonally arranged (or "diagonal-split") dual hydraulic braking systems are the standard for most front-wheel-drive (FWD) vehicles. In this setup, one hydraulic circuit controls the front-right and rear-left wheels, while the second circuit handles the front-left and rear-right wheels.
This design is a safety feature: since front brakes provide about 70-80% of a car's stopping power, a diagonal split ensures that if one circuit fails, you still have one functional front brake and the opposite rear brake to keep the car stable and stopping straight.
Examples of Cars Using Diagonal-Split Systems
In contrast, many Rear-Wheel-Drive (RWD) vehicles use a "front/rear" (black-and-white) split, where one circuit controls the entire front axle and the other controls the rear.

Oh yeah I double dog dare you
LOL. That's wrong. You are confusing brake bias with brake circuitry.
