In Reply to: It's better on dry roads in panic stop situations. posted by ghost of olddude55 on January 4, 2021 at 13:17:24:
I know that on my first motorcycle with ABS, a 1993 BMW with first generation ABS actuator tech, I could beat the ABS in the dry if I had a practice run to judge where the threshold of lockup was. But in a panic-braking situation, no way.
It was the same with my first car that had ABS, a late 90s Saturn, where the ABS was easy to defeat with a single connector pull. I could also beat it in the snow, because when it sensed lockup on a very low traction surface, it let off the brake pressure too much. So the best approach in the snow with that car was to threshold brake just short of where the ABS would kick in, rather than the recommended pedal mash.
The cars I've owned since then have just gotten better and better with ABS actuation. The ones we own now don't engage ABS too early anymore and don't back off the pressure too abruptly, so they are very non-intrusive. The only time I've had ABS kick in on me over 40k miles in my current car are when I've really needed it: a full-on panic stop on the highway in the pouring rain, avoiding a rear-ender, and a couple of times in the snow when there was slush or ice under the snow surface.
If I could beat it, it would have to be under controlled conditions and probably after a practice run or two. Under emergency conditions, there's no chance I'd do better, no matter what the surface condition. Without prior warning, it would take me a second or two to find the traction limit. The ABS system would find it in milliseconds.
I'm ambivalent about traction control, but I think it has matured to be pretty transparent. My first car with traction control was a 2005 Focus ST, and I found it to be meddlesome in the snow, and a non-factor in other conditions unless I was driving like a hooligan and intentionally trying to force oversteer in a really tight corner. But current systems are good in the snow. You can still turn them off (in most cars), but there's no real need to.
Stability control is just an extension of the above two technologies and I think it probably benefits most drivers, especially drivers of high CoG vehicles like crossovers and SUVs. For sedan drivers like us, it's probably not necessary nor harmful. Even if a sensor or connector fails, it's just going to disable the system and give you a warning, it doesn't brick the vehicle. So I'm ambivalent about it too.
When it comes to tire pressure monitoring, there is no downside aside from aftermarket wheels costing a few bucks extras. I can't imagine what objection you could have with it. How many drivers on the road checked their tire pressures regularly before TPMS, maybe 1 in 1000? The rest had no clue whether a tire was low until it was visually obvious and by that time it was down to 1/2 of rated pressure or less.
