Pontiac: Antilock breaks grabbing and locking on wet loose surfaces

While watching news clips of the recent snow storm, I noticed that many of
the cars were skidding with their wheels locked up. The cars were new enough
that they should have ABS. I speculated that ABS must not work below certain
a speed. Just speculation though, I do not know. Hopefully someone with
knowledge will post.

Yes they dont usually function below 10mph by design. Not much reason
for them to.

It sounds like you're refering to two different issues, I could be wrong
though. I can't see any connection between rotors not being turned &
anti-locks to grab on loose surfaces at slow speeds. If you have excessive
run out in the front rotors, or out of round drums, then you may experience
some pulsating in the brake pedal, but not the rapid pulses as when the
anti-lock brakes are activated. The other thing is I don't know if the
human eye can detect anti-lock brakes in operation while observing cars
sliding. The "anti-lock" function of anti-lock brake systems applies brakes
for a fraction of a second in rapid pulses (multiple pulses per second)

The wheels were locked-up. Poster "Bonneville" stated that ABS does not work
below 10 MPH. If this is the case we are given bad instructions on using
ABS. You know what I mean: "Stomp Stay Steer". It appears that they do not
prevent locking at slower speeds on icy roads. In this situation we would be
better off with the old way of skid control: take your foot brake regain
steering brake again.

It depends on the cars abs design. Some stop working at 10 some at 7
some at 6 etc etc. Tell me...Why do you need your abs working at 7mph?
If you're still sliding at that speed abs or not, locked wheels or not,
you wont be able to steer on that kind of surface because its to slick.
If you dont know your car that well then I suggest finding an empty
snow/ice covered parking lot and start learning your cars limitations.

Why is it everyone thinks that their cars should handle like James Bonds
very fictional Aston Martin?
