Re:
Part of the reason why motorcycles have the front brake on the right is because the throttle has almost always been on the right. Some military motorcycles had it on the left so that the riders could operate a gun while riding, but I digress.
You just can't put throttle and clutch on the same side because it is kinda hard to coordinate moving the throttle while grabbing the lever. (not that that stops racers and experienced riders from blipping the throttle during downshifts while braking with the front).
On bicycles the front shifter is always on the left and the rear is on the right. That means most of the world has everything that controls the front on the left and everything that controls the rear on the right. Kinda makes sense, TBH.
Come to think of it, it's kinda like how on almost all motorcycles both brakes are on the right and clutch and gear lever are both on the left.
V-brakes (and side-pull brakes on road bikes) clearly were intended for front-left too, the cable run (especially at the front) is just unnatural when setting them up with a front-right setup. Shimano (who originated and still is based in a country where they have the front brake on the right) doesn't even have a version for front-right setups, that's how common the front-left setup is. On a global scale, it really is just a very small minority that has the front brake on the right-hand side.
