They do. Volkswagens from the 80s and 90s that have solid dead rear axles "tripod" around corners.

Motorcycle exhausts are easy to swap out so people could easily take the MOT with the stock exhaust then swap the loud exhaust into place when they get home.

The extra bit of the lid houses the antennas, it's plastic to not interfere with the signals as much as the magnesium would have. I do wish they could have attached it better or made the whole lid plastic over a magnesium frame or something.

This isn't a group looking to make a potentially one-off product in an attempt to break into the industry. This is a different marketing and manufacturing model that is trying to mini-max the cost-to-quality ratio by only making products that have already sold. Similar production quality as other selvedge denim companies like APC or Iron Heart, and sewn in the US. The fabric they source is often of limited supply, either discontinued or small production runs, from high quality mills.

Yeah it helps if it is properly formatted and intended to be easy to read. Style takes effort. A lot of us let emacs handle the formatting - auto indent and something like paredit to move lists around. Once you get a feel for how the tools move things it is a bit easier to predict, but even then it takes someone putting in effort to make it maximally readable.

The game has an alpha version appropriately named save_breaker that gets regular if not daily updates. Some of the later puzzles are completely different, the second architecture has been replaced with a more advanced one that includes pipelining, and some new puzzles are still in the works. The new assembler is much more modular and many of the components have changed shape, with some having been removed or combined. The author plans to release it as v1 when stable but who knows when that will be. Breaking changes still occur occasionally.

The top of fig 3 doesn't accurately represent a string pulled down in the middle. A string pulled down in the middle would have no curve to it in the legs unless some force is acting on it, it would look like a V.

Qubes is a Linux OS. It's like if you took Fedora and installed xen on it and booted up some VMs and the windows for them opened within the base OS instead of in individual system windows. Plus some cool magic with the file system to reduce redundancy and how many times you have to update things.

Any plan to increase the dimensions the 3d map can be generated for? This would be fun for motorcycle ADV trips but we tend to exceed the 100km squared limit.

Yeah in emacs with paredit/smartparens/parinfer or whatever, it is both text and structure. With parinfer you change the text and the structure gets modified to match. With the other two you can change the structure directly with a command that has a silly but descriptive name like slurp or barf.

Feynman Lectures on Physics books. It might just be the right timing for me as I've only recently really started to grasp calculus and linear algebra, but a lot of things are clicking into place as I read.

Ah this might be an in-industry definitions thing[1], I was taught most anything thin, especially the pieces that are welded to the unibody, are panels. Not just the outer skin. So floor pan, pillars, trunk panels, roof, subframe, maybe control arms, etc are all panels. Basically anything stamped out of sheet metal. It is the way they're often constructed that leads to corrosion, thin pieces of metal in close parallel proximity are especially hard to clean. Think two flat pieces spot welded together one on top of one another as many seams are. I'm sure capillary action doesn't help those either. They'd have to be sealed in paint or epoxy entirely to avoid the seam corroding. Welding itself changes the structure of the steel and leads to corrosion near the weld. If not spot welded, a different steel might be used for the weld that has higher strength to compensate for welds weakening the steel - but to get that they trade-off higher carbon content, making it more prone to corrosion.

There are very few all-aluminum cars. Audi A8 was for a while and might still be. I am not aware of anything cheaper.

Depends on where you live, in New England the salted winter roads tend to win and few cars last more than 10 years before there are holes in body panels.

Got sources on your claims? All the sources for the second one, that I can find, say methanol and ethanol can be separated by fractional distillation, that it is isopropyl and ethanol that is troublesome due to their close boiling points. See for instance this patent https://patents.google.com/patent/US4013521A/en on purifying methanol
