  1. Short or long, it was wrong. Yes, no and maybe. We have to differentiate between the process of slowing the rotation of the wheel, and the effect of that slowing on the deceleration of the vehicle. The function of an ABS system is to control the rotation of the wheel assembly in order to allow the tyre to develop an amount of sideways force which is the force that results in steering. If the wheel assemblies of a moving vehicle stop rotating, the tyres will slide on the surface. A sliding tyre cannot produce any steering force. In fact, if you are in brake lockup, it is possible to turn the steering wheel from left to right and back without causing the vehicle to change direction. An ABS system is designed to release the hydraulic pressure being applied to the brake cylinders before the pressure reaches a point where the rotation of the wheel stops. The system is also designed to return the pressure thereafter so that the critical point is reached. Then the cycle begins again. That is why, if you stand on the brake pedal and keep standing on it, you will feel a rapid shuddering of the pedal as the pressure changes up and down rapidly.
  2. GON, there's an old saying, 'a cobbler should stick to his last'. It warns against involving oneself in areas that one lacks knowledge or experience. No it wasn't. It is designed to allow the braking system to slow the rotation of the wheel until the point of lockup, after which the tyre will slide on the surface. By allowing some rotation in the wheel. there is some tyre/surface friction remaining to allow the tyre to create a steering force, thus the vehicle can be steered, which is not possible if the tyres are sliding on the surface. The composition of tyres does affect the tyre/surface coefficient of friction. Harder compounds lead to lower coefficients. That's why the tyres used for racing are "softer" than regular passenger car tyres. Since ABS deals with brake application, the hardness of the tyres is not a factor in its effects.
  3. With respect to the rest of those of the fair-haired feminine persuasion, Leavitt is the epitome of a dumb blonde.
  4. You keep pitchin' and I'll keep hittin'.
  5. And there is the flaw in your flawless argument. The coefficient of friction between a tyre and a road surface is not consistent. By that I mean sections of road surface of the same construction can have different coefficients of friction due to the amount of other material on the surface such as dust, oils, water etc. The onboard computer of a car would not know what that coefficient would be at any instant, so it could not calculate a braking distance.
  6. Santorini's eruption did create a massive tsunami. Some think that the tsunami was the source for the Noah story, but that story has its origins in the valleys of the Tigris and Euphrates in Mesopotamia. ("Mesopotamia" comes from the ancient Greek words mesos ("middle") and potamos ("river"). It literally translates to "land between the rivers". )
  7. That whole northern coastline of the Mediterranean is the boundary between two plates. It's a pretty geologically active area. We are talking about a volcano near Kolumbo, but we haven't mentioned Vesuvius, which blew up around 1800BC, nearly contemporaneously with Santorini and again in 1944, or Mount Etna which is pretty active. Then you have those earthquakes in Turkey.
  8. Getting back to the original point of this thread, the dumb buggers at ANCAP have decreed that this anti-collision device has to be fitted to new cars. For what? To prevent rear-end collisions. Think about the circumstances when rear-enders occur. It is usually soon after rain begins after a dry period. The accumulated muck on the road surface get wet and slippery and drivers who are used to driving in a dry road that provides a higher degree of friction between tyres and the surface, drive in a similar way, but the degree of friction is much less and stopping distance increases. From what I understand, these "safety devices" will apply the brakes if a collision is imminent. That is most likely to induce a skid and the vehicle will slide into the one in front. I can't see the device preventing rearenders. However, these twits at ANCAP are inflicting added costs and complexity for the manufacturers and cost increases for the consumer. I wonder if these "experts" ever drive motor vehicles to work, or do they catch a bus.
  9. Apparently the paperwork to start the process is being drawn up by the Democrats. It remains to be seen how pizzed off the Republicans are to make them back the Democrats and impeach him.
  10. The claim by the media that a volcanic eruption is imminent is clickbait. In the article Red posted above, a respected British volcanologist rejected the idea of an eruption. While the reports of earthquakes are reliable, they are caused by the collision between the tectonic plate under Africa and the Eurasian plate. The African plate's speed is estimated at 2.15 cm (0.85 in) per year. It has been moving over the past 100 million years or so in a general northeast direction. It is pushing closer to the Eurasian plate, causing subduction where oceanic crust is converging with continental crust. It is true that there was a massive volcanic eruption at Santorini about 1600 BC. There have been more recent eruptions. These have been due to the build up of steam pressure as groundwater reaches the magma below. At present there are few indications that similar events are likely.
  11. The impeachment process has begun. Start at the 3:00 timestamp in this video.
  12. MAGA caps don't stop you getting a red neck.
  13. Jerry, In simple terms, if the market crashed, would Musk still be the richest person? How much of his wealth would represent things that he could say that he owns outright?
  14. I could never go over to the Dark Side.
  15. I read the article. The US has been involved in sanctions against Iran since the Islamic Revolution in 1979. Sometimes sanctions have been eased, such as the time $6M was unfrozen in exchange for 5 US citizens being held hostage (I learned that from the article.) Sanctions are just one of the tools of international diplomacy. There are no rules for their use, just what is convenient at the time. Over the past fortnight we have heard Trump bluster, but he has backed off when he sees the narrowest of winning scores on the board.
  16. I can see your point and I agree with your supporting argument, but you said it yourself, The intangible promise. I was talking about tangible things, like the car. While I may possess a document confirming the contract between the insurer and me, I cannot sell you or anyone else the promise. Sure, if I sell you the car, the ownership of the promise goes with the car, but that ability to transfer the promise was agreed to between the insurer and me when the contract was entered. If I sell the car with 6 months' rego on it, I can't recoup the associated contract costs I paid on entering the contract, not can I recoup the value of the premium that gained me the promise for the 6 months before the sale. So to me, the promise has no value at point of sale. Obviously, it has value to the buyer, but once the sale is completed, the promise has no value to the new owner.
  17. With six you get egg roll.
  18. You could read the book https://en.wikipedia.org/wiki/Civil_War_(film)

  20. No peekin!
  21. Have you noticed how quiet the MAGA people are, as their Constitutional Rights are being ridden over?
  22. But he wants the traditional owners of the land to bugger off and live somewhere else. Just because Jordanians and Egyptians follow a similar religion to the Palestinians, he reckons that those countries should open their borders to the refugees. Ask the Cherokee people how well that worked for them. As a result of the Indian Removal Act of 1830, more than 60,000 Native Americans from at least 18 tribes were forced to move west of the Mississippi River where they were allocated new lands. Prior to the 18th century, they were concentrated in their homelands, in towns along river valleys of what is now southwestern North Carolina, southeastern Tennessee, southwestern Virginia, edges of western South Carolina, northern Georgia and northeastern Alabama consisting of around 40,000 square miles. You probably have a fair idea of the differences in climate and ecology between those near-coastal locations and the plains of Oklahoma. No wonder that the Indian Wars lasted into the 1890s. He's also sucking up to the Saudis. Remember that the first leader he contacted after being sworn in was the leader of Saudi Arabia.
  23. I said during the heat of this discussion last year, 'let's see how EV sales stack up by December 2025'. You are talking about Tesla products, and the drop could, in fact, be due to Musk's politics, or they could be a result of market saturation. Give it time to see what eventuates this year.
  24. How do we determine if someone is "rich". For me to say that I am "rich" I would have to tally up the market value of what I own. But that market value is a reflection of what you would pay me for the ownership of, say, my car. To the common person, a thing which is not a physical object has no value. So it is said that Musk is the wealthiest person in the world, but surely that wealth is not totally in physical things. Isn't his wealth based on the value of his shareholdings? But what, in reality, is a share? A share is a portion of ownership in a company. Owning a share gives the owner the right to a share of the profits made by the company. A share only has real value if it can be sold. So while Musk has wealth 'on paper', that wealth can't be converted into a physical thing, let's say gold, until someone wants to buy it. If nobody want to buy it, then the share has no value. So, the majority of Musk's wealth is fictitious.
