Left-side traffic is not better than right-side traffic

" Having to look past another vehicle (if one is oncoming from the opposite direction) is a valid point. However, since both you and the other vehicle are in motion, the other vehicle will be in your way for a split second." And there can't be multiple vehicles? "At the same time, the chances of a vehicle coming in the other direction and blocking our view (even for that split-second) are minute indeed, given my opponent's own point that these are low-traffic situations." The odds are the same for your mentioned disadvantage coming to pass and for mine. It would appear they cancel one another out. " 2. The comparison between different countries is not fundamentally flawed. The comparison was used to confront my opponent's point that left-hand traffic has with it higher incidence of Road Rage. I have presented some data pointing that there is no evidence of that and that in fact the contrary appears to be true." Any data in which other variables than the one you are looking at are not accounted for is fundamentally flawed. It's a basic rule of statistics, and science. Another flaw is that the data is self-reported. "My opponent presented no data whatsoever to support his theory that Road Rage is a higher risk in left-hand traffic." I presented the fact that one can see the face of the other driver more easily, and, more importantly, once rage happens, the use of weapons is easier. " 3. Both sides are significant when crossing. That's true. However, immediate danger is always coming from one side or the other (right side in left-hand traffic and left side in right-hand traffic). A firmly in-built appreciation of the right-side danger in left-hand traffic systems is consistent with the right-hand rule. In the right-hand traffic system, there is no such consistency. We just follow our well-established response (sinc childhood). "Right-side, check right-side". Given that (unfortunately) most people do little thinking while driving (we are creatures of habit), this is actually important." Without constant reinforcement of having to look to both sides, whenever danger comes from another side it will be all the more unexpected and therefore all the more harmful. If humans are creatures of habit, you want them to develop the most exhaustively useful habits possible- not encourage them to use only the habits that are useful when things are going right. "4.* "And since when can people already on a roundabout only approach from one side?" Since the invention of roundabouts. I quote from wikipedia: "All vehicles circulate around the central island in the same direction, and this direction is decided by whether traffic drives to the right or the left. In left-hand traffic countries the circulation is clockwise; In those that drive to the right, it is counterclockwise. " (http://en.wikipedia.org......)" Um... clockwise and counterclockwise both include both left and right. That's how circulation works. It goes, ultimately, in both directions. "The problem with his contention is that, when driving a manual car, we HAVE TO change gears." In the middle of steering in bad situations? Isn't the changing of gears supposed to be done primarily when you stop, and when you're going straight? Least that's how I was taught it works... "I suggest that the simple task of turning on the radio or opening the ashtray can be done equally with the left or right hand without much concentration." Not at equal speed with equal accuracy. " 7. My opponent says that evacuating a vehicle sideways is wrong. He suggests that when we have milliseconds to save our life we should start by turning our entire body to the side and then jump out of the car on both feet. I must say this is an interesting (if unheard of previously) exit strategy. " Unheard of? It's a basic principle of how to go down if you have to go down fast, taught in most martial arts- take the impact with a roll, not head on. And I did not say both feet. Turn and lead out with your inside foot, you'll have more momentum to get away from the car, which is probably your goal if you are evacuating. " 6. Drive-through is indeed zero danger. But my resolution is not limited to safety. My resolution is general and includes also convenience." Many people are obese in the modern world. The more you drive the more you are obese, especially if you go through drive-throughs. You might as well AT LEAST burn the calories of turning your body to the window if you're going to be going through drive-throughs. Such is a benefit, however small. " 8. My comment about guns was not meant to be taken seriously. I did not consider my opponent's AK47 argument to be serious either. I believe it was a metaphor for road rage. However, my opponent has responded to me on this point and I thank him for that. Note however that I did not mention anything about legality. I could find sources about the numbers of guns available to the public in various countries." There are sources, available to the public, that keep track of all guns, legal and nonlegal? Then how do black markets survive? " nb: useful comparison need not require a country that has moved from one system to the other. It could simply use people who have substantially driven in both systems." Anecdotal evidence is not generally ideal :D.
