1. ABS is banned in Formula 1. That should tell you everything you need to know about whether humans brake as well as a computer
2. You only have one brake pedal. How can you achieve maximum braking effort without ABS if not all wheels have equal traction?
Not at all. It tells you something about whether Formula 1 drivers brake as well as a computer. Most humans driving cars have a very different level of driving skill from a Formula 1 driver -- especially when it comes to handling extreme conditions that they don't often encounter.
