The battery swap feature was implemented only to maximize California clean energy credits. Only enough infrastructure was built to claim the credits.

“In 2013, California revised its Zero Emissions Vehicle credit system so that long-range ZEVs that were able to charge 80% in under 15 minutes earned almost twice as many credits as those that didn’t. Overnight, Tesla’s 85 kWh Model S went from earning four credits per vehicle to seven. Moreover, to earn this dramatic increase in credits, Tesla needed to prove to CARB that such rapid refueling events were possible. By demonstrating battery swap on just one vehicle, Tesla nearly doubled the ZEV credits earned by its entire fleet even if none of them actually used the swap capability.”

Not sure where the author is getting their ventilation rates. ASHRAE 62.2* says

"4.1.1 Total Ventilation Rate. The total required ventilation rate (Qtot) shall be as specified in Table 4-la (I-P) or 4-1b (SI) or alternatively calculated using Equation 4-la (I-P) or 4-1b (SI).

Qtot = 0.03 Afloor + 7.5(Nbr + 1)" (in I-P)

Where Afloor is the floor area and Nbr is the number of bedroom. A 2000 square foot 3 bedroom house would be 90cfm or ~45L/s.

True, but "during downtime, only apps that you choose to allow will be available". You can configure a phone to only allow calls (and no other function), and only to a limited set of people, during downtime by adding the phone app to the "always allowed" app list and enabling communication limits as above.

It does. This falls under "Communication Limits" - you can define one set of contacts allowed "during screen time", and separate set of "specific contacts" allowed "during downtime".

Similar experience at the fruit company ~15 years ago designing a graphics scaling and compositing pipeline for one of the earlier high volume phone SoCs. It was originally designed with (de)gamma blocks before/after the scaling and compositing blocks to do it in linear space but the (de)gamma blocks were removed at the request of a graphics team because "nobody does that" - I recall the justification being that their assets were optimized for the incorrect behavior so they preferred it. I had a copy of Jim Blinn's book Dirty Pixels (aka the Gammasutra) that I would refer people to but it didn't change any minds. I hope they've improved since.

With the exception of some, but not all, newer GDI (Gasoline Direct Injection) engines, fuel injected engines have fuel injectors in the intake manifold upstream of the intake valves. Some GDI also have a combination of traditional injectors and direct injectors. It is inaccurate to say "the intake valve only ever sees filtered air."

The roadster was a “glider” (body minus powertrain) built on contract by Lotus, but it was not based on the Elise: it shared only a handful of parts with the Elise.

There are apps that do exactly that, e.g. NumberShield for iOS. Blocking calls from numbers with the same first six digit as mine has substantially reduced the amount of robocalls I receive.
