I wish overhead (cut away to passenger layout) and side scale drawings of all cars existed. That way you could directly compare the vehicles. You'd think such information would be needed (in the U.S.) by the NTSB; and, thus, be freely available.
- weinzierl 19d agoElectronics has this, more or less. Every device with a radio needs FCC certification, and the filings are public: internal photos (PCB shots good enough to read chip markings), external photos, test reports, manuals. Look up the FCC ID from the device label. https://apps.fcc.gov/oetcf/eas/reports/GenericSearch.cfm https://apps.fcc.gov/oetcf/eas/reports/GenericSearch.cfm or https://fccid.io https://fccid.io for a better frontend. Nobody set out to build a teardown archive, it just falls out of the certification process. I wish cars had the equivalent.
- thechao 18d agoIf the NTSB claims the car is safe on its interior in terms of certain kinds of crashes, you'd think that geometry & layout of the interior would be part of that claimed specification. That would prevent an A/B problem: the NTSB tests a car with 18" of padding, and the car manufacturer delivers a car with 18mm of padding. Or... whatever. Basically accountability & reproducibility.

- dllu 19d agoThat's not the same thing as those are photos with perspective distortion.
- IshKebab 19d agoPresumably they scale the photo to the actual measured dimension though, so at worst it will make the car look a bit weird.
- qingcharles 18d agoInteresting point. They need to photograph them with slit-scan photography.
- dllu 18d agohaha, I see you recognized me from my line scan photography work. But unfortunately that only gets rid of perspective in one axis but not the other. Probably just taking photos with a really long telephoto lens would be good. In theory, you'd use a telecentric lens [1], but then the lens would need to be bigger than the subject, which is not super feasible for a car-sized subject. I guess for line scan, the telecentric lens just needs to cover a small vertical strip of the car so it just needs to be really tall.

- qingcharles 18d agoHaha, I didn't recognize your username, but now I look at your blog it was your work I was thinking of :) Well, that screws my idea then. Best to just 3D scan the cars and model them in 3D with no perspective then!
- toasty228 19d agoSame, I recently upgraded to a similar car but slightly different segment, same brand. I couldn't find any data about it, I asked llms and they all told me given the available data the cabin size should be basically the same in term of passenger comfort. Completely wrong, there is much more space for both front and back passengers
- macintux 18d agoFor years, I've felt my dream application for my iPad would be a wireframe view of my vehicle that allowed me to explore the mechanical functionality as it moved. See the clutch interact with the transmission, see the 4-wheel drive engage, all while in motion.
