In the 3I you will have standards that date back to the First Imperium in some cases. These are going to be most common along the commerce mains where the marketing and delivery power of the megacorps overwhelm and reduce the need for local design.
True, but even then something might be a megacorp design and meet all the "ISO standards"* and yet still look completely different to another megacorp's design that's the same gross tonnage for the same function.
Why is DFW talking about hamster-power again? That was the other thread. This is a new thread.
Never underestimate hamster-power.
Now now boys and girls, we're all weird. Lets all try and get along eh?
Speak for yourself. I'm perfectly normal - it's the rest of reality that's bizzarre.
Vacuum environment protect is an option. If a vehicle doesn't have it listed in the description, then it doesn't have it. Range is listed for all vehicles. Fuel type is irrelevant, though if that detail is important to you, make it up. There are notes in book for adding fluff text to your vehicles, if your players are the type who like that sort of thing, including power plants and fuel types.
Fair enough. I think DFW and I must have noticably different player groups; mine are fine with this sort of thing. There is 'blatantly silly science' and 'not blatantly silly science' but as far as most of mine are concerned, once you reach the point that anti-gravity technology is available over the counter to the public from a genetically engineered sentient wolf, being too nit-picky about the science is not going to end well.
No Traveller vehicle design system has ever provided dimensions beyond volume/mass, so where that criticism comes from confuses me.
I wouldn't want it to, I think. Volume is something you can stretch to make a shape. I don't want you telling me that a ground car has to be exactly this shape; I might want anything from a stretch limo to a fat hummer. I may be misunderstanding the question, though, so please correct me.
However, when you are belting down a narrow city street, 500 story towers all around you, and the bad guys are following close behind, peppering you with gauss rifle fire, whether your air/raft uses hydrogen for fuel or the souls of lost children is largely irrelevant. What is relevant is how fast it can go, agility, range, hull, structure, armour, and weapons. This system provides what is relevant. You can add all the fluff you want.
I suppose the counterargument is that a lot of people use traveller for something other than 'bunch of miscreants in a clapped out starship'.
An investigator (
Judge Dredd) might be actively looking for details about a vehicle which are out of place, or are distinctive, and is likely to ask awkward questions.
A field commander (
Mercenary) is primarily interested in whether he can get the tank to the battlefront and what skills, tools and personnel he needs to maintain it.
A colonist (No sourcebook yet but I keep asking Rust to do one!) is primarily interested in the peculiarities of his environment, so things like weight, size and fuel availability are important.
However, these can be just fluff guidance - at least to me - rather than necessarily doing something to the Nth degree. As long as it's simple, quick, and doesn't contain anything blatantly illogical (like sloped armour being worse in practical terms), I'm looking forward to it.

Or whatever. Has it ever been said what the standards organisation/codes are called in the 3I?
