  • The gearbox only exists because the engine can only go so fast.

    Oversimplified. The transmission exists because engines are optimally efficient at specific RPM ranges and the transmission works to keep the engine in those ranges. It/you (auto vs stick) will also downshift to provide more power at the cost of efficiency if hard acceleration is required.

    When doing 130 you can essentially only see your own lane well, with rudimentary details in the other adjacent lanes

    If you can’t see adjacent lanes, then you’re not scanning properly. This is called tunnel vision and where I live you’ll fail a road test for it. You’d also fail for going 130km/h.








  • There are a lot of things that FDM printing will likely never be better than say injection moulding, and the main thing is speed, as in quantity over time. A single 3d printer might be able to make a plate full of maybe a dozen widgets in a few hours, and in that time, the injection moulding machine will have tens of thousands produced at a higher quality.

    On top, 3d printing would require more staff to troubleshoot, clean, re-start prints, remove scaffolding from finished items, sand/polish to remove the layer lines, etc.

    What it’s great for in an industrial setting, is prototyping. For example, a case for something can be printed, and the plate can be filled with several variants. If a flaw is found or changes needed, then a new batch can get whipped up on the same printer. Once a design is found that is acceptable, the CAD drawings get sent to have moulds created.
