It does depend on the car. I guess mine is a little heavier than others, and I get no skidding on a panic stop. I did get it with my previous Speedster - front wheels locked up.
As for ABS, I seem to recall we drove without that system for years, and we seemed to manage okay. People have lost driving/braking ability with all the computer assist on cars now.
And Lane, when a little kid runs out in front of your car, you aren't thinking 'I must modulate my braking...' 
It's a great theory, and maybe some can do it.
