| And if you're crawling along at 10mph in a traffic jam it isn't anyone's fault as the gaps can be much smaller. And if it's smashing down with rain the gaps would of course need to be much bigger. The safe distance between behicles is no more a constant on a given piece of road than the safe speed ... |

| If you drive in heavy highway traffic, you've probably seen a traffic wave develop at a construction site where one lane is blocked. You crawl and crawl at 3 mph until you get to the bottleneck, then you take your turn merging as the two lanes sloooooooowly come together. Then you race off at 60 mp... |

| back onto incident diaries ;). i don't keep one myself, although i might consider it now. I was involved in what I would call a close near-miss a few days ago. Initially, I was quite angry with the other driver, but after my annoyance had subsided I started to think about the near miss. Unfortunatel... |

| I think it all depends on where the test statistic (KSI/fatalities/etc) originally lay in comparison to the mean value. If the speed camera is removed when the test statistic was low in comparison to the mean, then regression to the mean will occur and will make it look like the removal of the camer... |

| I found an intriguing article on traffic flow here: http://www.amasci.com/amateur/traffic/trafexp.html Whilst the author doesn't make out that this is 100% correct, he does have some very good points. Perhaps if drivers were taught theory like this, we could reduce congestion on all types of road. |

| The question is, why didn't the vehicles in lane 2 move into lane 1 after they passed the previous vehicle in that lane? 1. Lack of understanding of motorway lane discipline? 2. Lack of confidence - i.e. I don't like changing lane so if I stay in lane 2 I can overtake and others can overtake me? A ... |

| I'm paraphrasing because I don't have it to hand but it advises that once you have passed the vehicle you were overtaking to move back to the lane on your left. It goes on to say that you shouldn't however be 'overzealous' (I think that's the word used) to the extent that you are constantly changin... |

Does anyone feel that they fit into the category of 'bad passengers'?
By 'bad passenger', I mean someone who is at considerable unease when others are driving them. I tend to try to switch off (observing the road/conditions critically) when others are driving, which helps a lot. |
