In fact, anti-lock breaks can CAUSE some accident.

Some reasons:
1 - Usualy, only one rotation reading per fotation.
2 - They are NOT progressive. It's all or nothing. It can literaly jerk 
your foot off the break pedal.
3 - Been all/nothing, they can realy shake your car around, possibly 
quite violently.
4 - In an emergency, if you brake near the sliding point and ONE wheel 
slips a little more than the others, ALL breaking stops, then comes back 
at FULL force, possibly causing all 4 whells to lock.

Correctly implemented anti-lock brakes should have multiple analog 
sensors of multiple parameters:
Braking tork.
Suspention load.
Continouus rotation speed: e.e. arount 100 reading per rotations. Most 
have less than 5...
