Interesuju me vasa misljenja posto na mojim kolima nemam ABS, izvinjavam se sto kopiram tekst na engleskom:
ABS.
I read an article in Popular Science in 2004, and one of the comments in it struck a nerve. The author said that (paraphrased)
"Drivers are resistant to new technology, but will inevitably get used to it. When ABS was first introduced, a lot of drivers didn't trust it and thought it would actually increase their stopping distance. Now though, even the most hardened critics wouldn't be without it."
Obviously I'm not one of those people then. I think ABS is a blight on modern car designs which causes more dangerous driving and more accidents than it prevents. It's also a pain in the arse. For example - try braking gently as you're going down a moderate hill. If you hit a bump in the road, as the wheels rebound from the bump, most ABS systems will interpret that as lockup. When they do, they brake pedal vibrates and you suddenly find yourself stopping a lot more quickly than you'd intended - the car has effectively taken control away from you. This is invariably followed by a horn and the squeal of tyres from behind you as the next car back is presented with a very sudden stop for no reason. Very dangerous. Another example : emergency stops in snow and ice. There's not an ABS system on the market that can make you stop quicker in snow and ice than good old fashioned driver-powered brakes. The reason is simple. When the wheels lockup, they dig-in to the snow or ice and work their way down to the road surface. With ABS, they just skip around, as you sail merrily into the vehicle in front because the ABS just registered all the wheels locked up and took the brakes off. As a final example, take the one they show a lot on TV : the car braking and swerving around the tractor pulling out of a field on a muddy road. This simply doesn't work for the same reason as the snow and ice above - the wheels lockup because they're skating on wet mud. If they stayed locked up, the tyres would dig in and you'd regain control. Instead, the ABS kicks in and takes your brakes off for you. *SLAM*. Right into the side of the supposed tractor.
The problem with ABS is that it's a placebo designed to put to rest the fears of the bad drivers. They think that ABS means they can stop in any situation, which is wrong. It makes people more dangerous on the roads because of this false illusion and I reckon more accidents are caused now by people trying to rely on ABS when it really doesn't work in anything but ideal situations. ie. bone dry, billiard-table-smooth road surfaces.
I wish there was a way I could disable the ABS on my Subaru. I felt a lot safer in my older vehicles which had a pure mechanical connection from my brake pedal to the brakes. The intervention of ABS in my current car scares me to death every time I have to use the brakes, because I don't trust it to not take control away from me. I shouldn't have to drive around constantly wondering "is the car going to override what I want it to do?"
The hidden gremlin of ABS - what they don't advertise.
If you look at the statistics for crashes, a large percentage of them are "fender benders" - low-speed impacts that only do a little damage and so slow that the vehicle occupants are in no danger. Less than 15mph normally. I'll give you one guess what the typical "minimum activation speed" is for ABS. That's right. Your average ABS system is useless much below 15mph. Seriously. Try it yourself. Find an empty road on a slight downhill grade - even better if its on a dewy morning. Run your car up to about 15mph and jam on the brakes as hard as you can. The car will skid to a stop and the ABS system will remain totally silent. Absolutely true. So ABS doesn't help prevent the accidents which insurance and safety companies tell us are the most common. Go figure.
