Ice is precisely the type of situation ABS is built for.
After front wheel drive, ABS is one of the major ways to improve winter driving. Not only in snow, but in black ice and similar conditions. The big issue is driving too fast and losing control and going into the ditch or a spin.
ABS makes it easier for you to know you have a problem and to avoid it. It may or may not bring you to a full stop in a shorter timeframe, but it will shed speed so you regain control.
After ABS, all season tires and AWD are the most important enhancements.
Agreed. But I would say the proper tires for the conditions is ideal, meaning snow tires in winter.
- ABS for steering control.
- Snow tires in winter ("snow boots for your car").
- AWD (or something adaptive) for traction control.
- Last but not least - driving smart (not speeding, adjusting for conditions, etc.)
And slowing down. A 10% reduction in speed results in ~19% less energy for the brakes to dispel - aka a disproportionately shorter stopping distance.
Also, I find the electronic stability control system extremely useful for detecting black ice. A slight acceleration attempt provides instant feedback if the road is slippery, but not immediately obvious.
It applies equally to snow, wet or dry conditions.
So what you're saying is they should have been going slower due to inclement weather?
Edit: removed part that was saying ABS is useless on ice.
