Today when rocking out of a snow bank I almost ran into a telephone pole because my ABS gave me a hard pedal instead of applying my brakes. Luckily at the last second the hard pedal freed up so I could skid to a stop. Also, when rocking out of the snow bank, you have to wait for the ABS to stop the wheels before going to F to R or R to F. I wish there was a button to turn off the ABS like you can with the TCS.

Just my biased opinion but I think it was due to the ABS that you avoided the pole. It is many times more capable than humans.
The worst time I have with ABS is when the left wheels are on bare pavement and the right wheels are on snow. As typical, the snow melts off the road starting from the center out. The left wheels have plenty of traction to stop the truck, but since the right wheels slip, the ABS releases the brakes on the left. ABS prefers to crash INSTEAD of allowing a wheel to skid! In real bad cases, I mash on the park brake and stop almost instantly!
Yeah modern ABS systems are nothing but a hazard on snow covered roads, they need to do a much better job of calibrating them or develop a selectable system with a snow setting

They just need a manual ABS OFF button. My beemer motorcycle had one for off-road terrain. It just reverts to conventional brakes.
On an older Chevy truck that my brother had, he would just pull the ABS fuse.
The problem now days is that everything is integrated with the computer. It would probably have a hissy fit if you disabled the ABS!
Isn't it a shame all of the nannys that we have to put up with because the general public is so stupid?
I sure miss natural selection!
I may be wrong here, but my understanding of anti-lock brakes is that they only work when the brakes are slammed on and held down, creating a pulsing of the brakes to overcome the natural instinct to slam on the brakes in an emergency. If you don't want the abs to kick in, don't slam the brakes to the floor. Increase following distance in rain or snow and slow down so you're not overdriving the conditions. I drive a tractor and trailer and have logged close to a million accident free miles and I can't tell you how many people pass me doing 70 mph riding 3 inches from the car in front of them on snowy or icy roads. Then you see them in the median a few miles down the road.

I've driven half my life without ABS and I never died because of it. I was only going around 10-15 m.p.h in reverse when the big-brother ABS hard pedaled on me. If the truck would of at lease give me some input I won't be free-wheeling towards a telephone pole. ABS is for people who set their cruse controls on slick interstates and not for the off-roader.

I was going 10 m.p.h in reverse, I don't think I was overdriving the conditions.
You weren't overdriving the conditions with speed, but with brake pressure. Abs doesn't kick in every time you press the brakes. It only kicks in when you press the brakes hard enough to lock the wheels up. If you had gently applied the brakes, abs would not have been activated. When it realized you applied the brakes too hard it pulses the brakes(press to the point of locking up, release a little, press to point of locking, release a little, repeat) but the brakes are not "free wheeling." A vehicle stops better when the wheels are turning and maintain friction than locked up and sliding.

Yes, as a mechanic myself, I understand how ABS works. All I'm saying is that ABS sucks.

Reason: edited spelling in my post.

If you did not have abs then you would have pressed your brakes hard enough to lock them up, which would have resulted in your truck sliding into the pole. The abs kept your brakes from locking up but still provided the necessary friction to stop the truck faster. If you hadn't pressed your brakes so hard the abs never would have activated and would have stopped without your wheels locking up or abs kicking in to save the day. If you don't like abs, don't throw the pedal to the floor.
Tom will agree that I am usually one of the first ones to complain about modernization of vehicles(i hate automatics, power windows, locks, etc), but in this case abs kept you from hitting the pole and never would have been activated without too much braking to start with.
I remember some scary braking: one involved my four drums got heated and then needing to make an emergency stop (NJ Parkway). Another time I was descending Mt. Washington, behind an old pickup with a granny gear, again leading to hot brakes (all discs). Fortunately I got thru those earlier years.
I may be an old fuddy-duddy but I prefer todays brake systems.
All I'm saying is you were driving too fast and blaming your brakes for a near miss. 10 MPH is a dead sprint for most people.
Lots of folks drove most, if not all, of their lives without ABS without a problem. Until they had one, and hopefully they survived it.
I was getting myself out of a snow bank, I was just spinning my wheels by *****-footen around. And yes, I blame brakes and the engineer(s) who had designed my brakes for my near miss. I've had many cars that had ABS and they all braked when I wanted them to. Lastly, if ABS was so life saving, why is there so many fatal car wrecks everyday? According to your world, no one wrecks when they have ABS.
