  • At the cost of the mold to do something like that (and the machine to even run it), I’m reasonably sure that stamped or brake pressed frame rails make more sense cost wise. I’m not sure that volume will ever drive the cost of that low enough to be worth it within the life of a mold like that. Like, I can picture the design to make it a basic two plate mold (I think, I’m more used to parts that top out a bit over a foot in the largest dimension), but then the gate size and shot volume I’m picturing to fill the thing is just bonkers, although apparently there are a few machines in the world that could theoretically do it if I’m reading their specs right from a quick search.

    Unless your thinking a carbon fiber layup, which is feasible, but I believe metal becomes more cost effective again at that point.









  • Honestly, the 85 percentile rule, when actually used, is about the same as RNG, but with a bias for higher. Iforget where I saw it, but from what I remember seeing even the 85% rule gets deemed as too resource intensive so a speed limit from a “similar” (for some random definition of similar) road’s speed limit is used.

    I feel like it was something in the vein of a Strongtowns or Climate Town video.

    Edit: Which now that I think about it, I’m reasonably sure the video also referenced the MUTCD.


  • It’s bad road design. US roads are nearly all designed to encourage high speed travel by being mostly straight, perfectly smooth (well, until weather happens), and super wide. Then we slap a random-ass speed limit sign down and say “job’s done.” If roads were a bit less wide, even if just painted narrower, not dead fucking straight, and if you want to get fancy use something like how the Dutch use bricks for lower speed road surfaces, the road design alone would encourage lower speed driving.
