Historically people drove stick. And clutches were hard. Like seriously hard. I remember driving a tractor when I was 10 and I had to use my whole body weight to move the clutch.
So people's left foots were not sensitive enough for the break. Whereas the right foot was trained on the soft accelerator.
As a stick shift driver, it took me years to learn left-foot braking without stomping on the break and coming to an immediate full stop. But left-foot braking comes in very very handy on snow and gravel. It's also a lot of fun.
PS: modern clutches are soft, but you still usually either depress it fully or leave it alone, which means your left foot isn't too well trained in applying varied degrees of pressure
