To continue on my crusade against Polos in that other thread:

Polo ignores the solid line 300 meters before an offramp off the N2. Polo pushes in at the last meter, causing the car behind him to slam brakes, he nearly careens into the island trying to avoid said Polo and this knock on effect continues three or four cars down.

The same Polo gets to a set of traffic lights which are extinguished due to LS, and while everybody is treating it like a four-way stop, he decides to just drive through it as if it were green. The car that was already in the intersection did not look happy.

A few intersections later I catch up to him and see he also has no working brake lights at all - I'm surprised he hasn't been rear ended yet.

The Polo that stopped behind me also had a driver that was glued to her phone and just about stopped up my exhaust pipe from braking too late. I managed to get away by the next intersection and changed lanes. I don't want a Polo stuck up my boot today so I try and give them a wide berth if possible

Jy's darem Polo befok!:whistling:

if you brake hard enough trust me it will skid even with abs and traction control.

No it wont. Go do your own tests or read up on how ABS works. Anti-lock braking prevents wheel lock which causes skids. If the car detects any skidding, it will modulate the braking to prevent skidding.

Your car will not go into a skid unless you lose traction on lateral axis which usually happens during fast cornering, where abs is pretty much useless. You'd need traction control and EBD to help you out there.

You can be doing 120km/h and slam on brakes. Your car won't go into a skid.

You are both right, ABS will prevent locking of the wheels at a speed of over 40Km/h, but under that it is effectively disabled and the wheels would lock up (but you are generally stopped by then.)

Edit- The speed should be a point between 16 - 29 Km/h (10 -18 Mp/h.)

To miss CA 786-915 in your BMW

Im here to help you with some pointers

1st up, you need to work on your lane changing skills. For one, you cant somme Jass turn into a lane as you feel like it, If you did not notice you almost hit my car in the middle on the side, i would assume this is because you where too busy on your cute little iPhone to check if there was actually a space for you to change into, I mean for what other reason would anyone pull such a stupid Cnt move, right?
Also there is this cute little thingy on the side of your steering wheel called an Indicator, this is to notify other road users who do not drive a BMW that you are planning to change your lane (bonus tip, switch on this indicator BEFORE you change lanes)

and finally, when you do this in traffic do not be surprised when that very same person later cuts you off :ROFL: :ROFL: You seemed so surprised when I looked up in my rear view mirror, the look on your face was absolutely priceless. Im still trying to decode the sign language you where giving me for the next 9 Kilometers in traffic either that or you wanted me to see something up in the sky?

I think what Im trying to say is, Dont be a Do0s... Be Lekke instead. Were all on the same N1 in the same traffic on the way home too. your BM does not give you special rights at all, the sales guy lied.

Source that ABS is disabled under 40km/h? Can't find any info on the web.

ABS is less effective at lower speeds, but I have never heard of the system being disabled under normal conditions.

Rereading my post, you are right I could have explained it better, disabled perhaps being the wrong word, "less effective" does sound better.

I first heard it and was shown it on a BMW driving course on a skidpan, this was a few years back so no doubt the newer tech is better and my info might be out of date.

I was interested and then asked my brake expert about it. The cut off speed is not a fixed value but a guaranteed point at which the ABS is still fully able to control a large speed differential between the sensors and mechanically act on it. In actual driving, depending on conditions, the lower limit of functioning might/would be lower than that.
For the most part the ABS system is rarely triggered, but when it is it saves lives and one of the best safety items on a car or truck.

If your car has ABS fitted, either on a skidpan or a deserted dirt road (tarred roads are a bit "bitey" in my experience) jump on the brake pedal as hard as you can and you will feel and hear the pulsing until you are almost stopped and just at the last moment your wheels lock up, it certainly does on my car.

There is another( perhaps better) explanation from a chap at Bosch here https://www.quora.com/At-what-speed-does-abs-system-stop-working .

Edited the speed reference.

LOL!

ABS works independent of speed. You can be doing 200ks or 10ks per hour. If it detects the wheels are slipping it kicks in.

:laugh: Did not phase me at all, I was on two wheels.

There was some bad driving down that dip though. I stick to the dirt as far as possible but have to go into the yellow lane to cross the driver. Had a taxi doing some yellow lane driving forcing me off the road and having to wait for it to pass.

Rubbish. You're talking about supposed ABS's effectiveness... That has nothing to do with its operation. ABS will kick in if your wheels slip. That's its core job and will work every time unless your system is defective. If it's "bitey" then that's a result of the car you are driving - it has nothing to do with the system.

I expect no better from CL drivers. :ROFL:

They're up there with CY, CFM and CF drivers. The worst in Cape Town
