  • There is a quick fix, sealed beams.

    There was a time when all cars in the US had round headlights. That’s because there was only one headlight and all cars were mandated by law to use it. That law can be reimplemented at any time. It would fix the headlights as soon as it goes into effect.

    Car makers would hate it. It would ruin a lot of their styling and marketing having to use the one and only headlight. Which would make it an effective deterrant. Any major government using sealed beam laws as a threat would make the industry self regulate quickly.






  • Found the location on street view. The bus lane is a weird partial bus lane that only exists on part of the block. Most of the lane is available for parking.

    The bus lane areas are painted red, and there is a sign at the start saying no parking/tow away zone. But they aren’t aligned properly. The red pavement starts about a car legnth before the no parking/tow away sign.

    In most traffic codes, signage takes precidence over painted markings on the street. So as far as I can tell, the truck in the picture is parked legally, despite being on red pavement.

    This is some particularly stupid street design, and this post is an incredibly manipulatively framed picture, with the sign just out of frame, but not an example of illegal street parking.






  • From the article,

    terrain Boring will have to navigate: the tricky, sinkhole-prone limestone bedrock of middle Tennessee. The construction risks range from collapsing the ground beneath a heavily traveled state highway, to knocking out utility connections, to flooding the tunnel with groundwater.

    The ability to cut the rock is not the only challenge in boring tunnels. Regardless of the type of rocks it runs through, making tunnels using a TBM is one of the slowest and most expensive ways of making a tunnel. Its best to use other techniques, unless a TBM is the only option, which it isn’t for this project.

    The proposed airport line runs directly beneath sr41, and the second line is under sr70s. Just like Vegas it goes directly under preexisting roads, so they don’t have to deal with the administrative headache or costs of acquiring the rights to dig under private property. In cases like this it is far cheaper to use cut and cover.

    In cut and cover, you build a shallow tunnel by digging a trench, putting the tunnel in the trench, then burying it. Its the most cost effective way to make urban metro tunnels in most cases, but it does require shutting down part of the road to construct. However those carbrained enough to think chauffeur driven cars are mass transit, will consider temporarily closing a few lanes on the surface during construction to be unacceptable.


  • Cities will start and end school zones within a quarter mile of each other. The safer option would be to have the street stay a school zone for its entire length, but no. I’ve seen many cases of “end school zone, speed limit 35” signs just before the start of a school zone. There’s no way that isn’t fine to farm tickets at the expense of children’s safety.

    American streets are dangerous for children. The solution should be to make the streets safe, everywhere all the time. A temporary speed limit in a few spots doesn’t fix anything.
