In fact, I've seen multiple times where I'm already up to speed in the merge lane and well ahead of the car in the right lane as the solid line of the merge lane becomes a dashed line, but the idiot in the right lane decides to accelerate such that they near-miss pass me AS THE DASHED LINE OF THE MERGE LANE HAS COME TO AN END. So, they are the problem because they very recklessly cut off my legitimate merge opportunity due to their own MFFY tendencies. |

How can they accellerate quickly enough to keep you from merging,if you are "well ahead" and moving faster than them? If you were "well ahead",what were you WAITING FOR???? The opportunity to merge was there,and you dawdled,and lost it. And then you expect them to hold back and make way for you. It appears you are a "last-minute merger". > > So, they are the problem because they very recklessly cut off my > legitimate merge opportunity due to their own MFFY tendencies. > > > No,it's that you apparently never learned how to merge properly in the first place,and expect others to make way for you in spite of your errors. -- Jim Yanik jyanik at kua.net |

Do try to keep up. >Why not try to figure out how your driving style is >slowing down the general flow of traffic. Since my driving style is "I'll stay out of your way, just as I would have you stay out of mine," it's blatntly obvious that my driving style is not slowing the general flow of traffic down one whit. This is in stark contrast to PLBs who refuse to speed up or stay out of the passing lane because they claim they're driving "fast enough." These people are like a rock in a stream - the flow is forced to slow down and go around it. |

An intelligent car /roadway *system* can be fitted with many more sensors than a human could possibly have, and wouldn't get distracted by cell phones, big macs, or budweisers. It could do a far better calculation of stopping distance than a human based on tire type, temperature, dynamic surface friction and other variables, and could constantly be on the lookout in all directions simultaneously - something a human could never approach. And car to car data sharing would be far more efficient than a CB |

And the entire merge lane is there for me to use, right? Or now is it--according to the MFFY speeder/race-driver mentality and mantra--must I cut in sharply at the first available opportunity even though the merge lane defines all the usable space I can use to complete my merge? > > > > So, they are the problem because they very recklessly cut off my > > legitimate merge opportunity due to their own MFFY tendencies. > > > > > > > > No,it's that you apparently never learned how to merge properly in the > first place,and expect others to make way for you in spite of your errors. > I say again--as the solid line goes dashed, there are two headlights in my rearview mirror, and then when I make a double-check to the left before I make the merge, the idiot is passing in a near-miss manner. Sorry, I still assert it's 100% of the idiots fault. And no, it's not that I didn't learn how to merge properly--it's that I am entitled to use the entire merge lane as needed, and no race-car driver mentality is going to rush my merge since the lane(s) to the left are available passing lanes. Just because the line goes dashed does not mean I need to cut in immediately... especially in the case of the idiot, it's even better that I use the entire merge lane or else the idiot would probably end up hitting me from behind instead of near-miss passing me. After all, that's also merging from the rightmost lane, which does double as the slower traffic lane. Instead, the impatient MFFY drivers should feel free to merge left into the passing lane is passing is such a high priority. Too bad if you disagree, because that's the way the roads have been engineered... too allow mergers to use the entire merge lane. |

(YIKES!) A human driver performs the same task, without all that much trouble. The DARPA rules aren't unreasonable. -- There's no such thing as a free lunch, but certain accounting practices can result in a fully-depreciated one. |
