The technology -- that is, the hardware -- may be different, but the physics is the same. You can afford to brake more with the front, just like before.

Find out how much lever pressure it takes to lock them up, then, well, don't let the front lock up.

Comparing a car's ABS to any bicycle brake isn't a valid comparison because ABS is electrically driven and makes the pedal feel completely differently when it's activated (if your car's brake pedal never went "rr-r-rrrrr-rrrr" under your foot, you never really used ABS).
