That's true, that 1g is not necessarily the maximum braking force due to any rule or constant. Vehicles can theoretically brake harder and stop faster. But practically, with rubber tires and pavement, it's a pretty good approximation of the best you can do.

A 1g stop from 60 mph takes 120 feet. The best street vehicles in the world are in the 110 feet range, and the worst you'd ever want to drive would be in the 140 feet range. Motorcycles aren't far off of those numbers either. They are lighter, which helps to some extent, but they have smaller contact patches, which hurts to some extent.

Now with race tires on a vehicle with ground effects, these numbers ramp up quickly (think F1).
