| Yea I don't get why the lights take so long here. There is a crosswalk near my house (only a 3 way intersection) and I have to wait 3-4 minutes before crossing as one side goes first, then the other, then the other, then the 2 left turn lanes. Sometimes I just say eff it and jaywalk. |

| Oh yeah, what's with these idiots who tute their horns at you repeatedly when your at a red light and in the far right lane. The arrow on the road indicates go straight or turn right. It says both. So, I'm there to go straight. I'm not going to get behind a long long lane of single cars that takes forever to go when the light turns green. |
Because you can turn right on red. I'm not sure if your state back home had that, but mine did and anyone who was going straight but in the right lane was expected to pull up a little to let the cars behind turn right on red. People who didn't do this were considered rude and selfish.
In the future you should help improve the flow of traffic by avoiding the right lane and keeping it free for people to turn right.
Other than that, for driving I just put on really mellow music- Classical, opera, chill R&B, jazz, coffeehouse music, etc. and just drive like a grandmother. Leave 5 minutes earlier and cruise. I like the slow lane and 4 seconds of space between me and the car in front, and a smooth ride. |

It's becuase it's on a "dumb" system as opposed to a "smart" sysytem using traffic regulating technology. There are no sensor pads under the roads to sense if cars are waiting or not. And a lot of ped crossings dont have buttons. It just goes through the cycles regardless of there being no cars waiting or 100 cars waiting. |

Take an M bus if you can. No standing allowed and the governor (buzzer) keeps the drivers from speeding on the highways, which is actually kind of frustrating since they have the bus lane and all.
The only problem is some of the drivers will drive lid a bat out of hell once they're off the highway to make up for the time lost to not being able to speed. Other than that they're almost always more professional than other bus drivers. |

This always surprises me. All I can assume is it's cheaper? |

No it's the same. I refuse to drive during peak traffic times outside of my work commute (happens to be relatively easy-going).

Who knows. I'd guess that when it was all set up, traffic was much lighter, and vamping up the infrastructure comes off as a logistical nightmare for the traffic guys. |

The system was designed more for safety. Before they installed cameras everywhere, many drivers were doing 160, 180 kph regularly. So the lights are more about slowing drivers down for the purposes of safety rather than getting people to their destination as quickly as possible. |

That's it, and it will save gas if done properly. Those who pump the accelerator non-stop just that aren't bright enough to understand how to do it properly, which is to smoothly accelerate for a couple of seconds, take your foot off the gas, let the car coast and then accelerate smoothly again when the car slows down to 5km/h-10km/h below the speed you want to go. |

Can you give some evidence that that actually works? Slowing down and then having to regain momentum to get back up to speed doesn't sound like a way to save gas. |

Bah - 'Coasting in neutral' seems to much more energy efficient! (same article). In fact, I think I should also add 'brake-free driving' to the list^^ |

| This does not save gas at all. You can't just make up energy. It takes more energy to regain speed then it does to maintain a speed. |

It will save gas. I just didn't explain it properly. I hadn't done it in a while, so I did today. At the most, the speed fluctuated by 2km/h. The key is not to look at the speed, but listen to the idle of the engine. Depending on the car and the road conditions, you can coast for 5-10 seconds on flat ground before you'll notice a drop in speed. |

Much of that Wiki article was dealing in hypotheticals. And the real savings is from coasting, which a bus can't do.
The idea of running the engine in its most efficient torque range makes sense but seems difficult in practice. |

It is ironic how one of the main sources for this article, who says it's theoretically possible to double or even triple one's fuel economy by driving this way, happens to be KOREAN! |
