Comment on xkcd #2929: Good and Bad Ideas

It’s also a three-wheeler, which gets around US safety regulations. It gets registered as a motorcycle or autocycle (depending on how your state handles it). However, it’s still an enclosed metal box. There’s not a lot of good data, but it’s arguably better to be sitting loose on a motorcycle with a helmet and safety gear as opposed to being crushed inside a sardine can.

There’s a certain point of shrinking cars where you have to ask “why not use an e-bike?”, and this is that point.

Well, it has a carbon fiber frame with a crumple zone in the front. They are going to put it through 3rd party safety testing. It won’t be as safe as a big SUV, sure, but I think it will be safer than an ebike. It also protects you from weather and has 35 cubic feet of storage in the back. I think ebikes are great too, but this does have more of the advantages of a car.

  You know how the Internet made fun of Stockton Rush for using carbon fiber in a sub, which is a compression structure? Similar thing going on here. Carbon fiber is a great material for tensile strength and lightweight. It can be used in compression structures, but it needs more careful engineering to pull it off. The benefits do not always outweigh the costs.
  
  As a more general issue, if a car the size of a Geo Metro or smaller can’t be safe on roads, then motorcycles and bikes can’t be, either.

    Well, I just said carbon fiber, but to be more exact it is forged carbon SMC, so yeah, careful engineering involved. Same stuff Lamborghini is using for some structural components, so probably fairly fit to purpose.

Cuz you can haul more, camp inside of it with the tent mod, travel further and faster.

  I’m not sure you can haul more. Cargo e-bikes can do a lot more than you think.

    Ya I saw that cybertruck to cargo bike comparison. I automatically went to the mountain bikes. We don’t have the same cargo bikes the Dutch have but there is a guy around here with a cargo e-trike. I bet it’d be close. But the car can also take a second passenger not in the cargo space.
