ELI5: Why we shouldn't use 2 feet for the accelerator and brake pedals in a car.

I've always heard that when driving a person should use only 1 foot to control the pedals. Wouldn't using one foot on each increase reaction time for breaking and accelerating?

Consider the brain's confusion trying to differentiate the need to press hard with the left foot versus the right foot. If you need to brake NOW! you're likely to stomp both feet. If one is on the accelerator and one on the brake, you've got problems. It's far better to separate the accelerate and brake decisions by making you physically shift one foot fractionally.
