Weight-Weenieism should be measured in percent of expendable income per percent of system weight. 20% of expendable income per 1% of system weight. With expendable income of $10k/ year, a 180 lb rider on a 20 lb bike can spend $1,000 to shed 1 lb from the bike without being unreasonable.

I'm setting up my 2nd Pro Miyata. (First has epic rust. Sweet, sweet ride so a total keeper but finding the exact same frame without - I'm going for it! The new came with parts. A nice racing, aero Shimano. Single bolt but with a set screw to adjust tilt. Never saw that before but I like it. I was riding a 2-bolt grey anodized SunTour that I figured was an MTB post (as opposed to the polished aluminum finish of my more expensive SunTour).
So, what the heck. I've got both posts out of their frames. Might as well weigh them. (4 kg scale I use for coffee.) Knowing full well the racing Shimano post was going to weigh less than the MTB SunTour. Shimano - 270 gm. Not too bad. Put the SunTour on. 200 gm! Wow! Guess its staying my ride.
2 1/2 ounces off. What can I do next?

) there is a a time for weight weenieism and and a time for style...... style should win in this case.

I agree with you that privately-owned public GROUND transportation has not proven to be widely successful. That said, there may be examples that I'm not aware of. In my limited knowledge, it seems like most current systems rely heavily on tax money. I suppose services like Uber could be considered "privately-owned public transportation", but I assumed you meant vehicles for hauling large quantities of people (bus, tram, etc.).

The comment about the "gas-pipe garbage scow" made me instantly think of the plumbing aisle at Lowe's and whether you could build a frame out of galvanized steel plumbing pipe. Or for the WW among us, PVC pipe. Just curious...I have a friend who wants to know.

I really like to ski uphill. The snow has been bad off piste this year so I’m slacking, but usually it’s my go to.
My Technica’s feel like cast iron cookware compared to my wife’s Scarpa’s. And my skis individually are only slightly lighter than her pair.
I never thought much about it since we both move about the same speed up and she’s tiny. I only get passed on the skin track by others if I take the ill advised 4th lap.
Then I made the rookie mistake picking up (lifting, not buying) some proper Skimo setups. Holy crap!! It’s even lighter than my wife’s teeny setup and some models even fit crampons (it’s been at least 10 years since I’ve ice climbed, but that’s not the point).
I’m all screwed up. Hot and bothered by my lead cored planks. Browsing the net. Trying to justify the expense.
I’ve already got a titanium spork.
Maybe I can drill holes in my water bottles?

Let's see - I spent about $600 to build up my new mixte about 6 lbs lighter than my last mixte build.
Lighter frame: $175
Lighter saddle: $140
Lighter seatpost: $122
Lighter crank $165
At about 3 lbs difference, that's about $.44 per gram.
No rack, bag, or kickstand - free
It's perhaps another 3 lbs lighter without the stuff inside the bag - a lock, tools, and spares, but less flexible and capable. The 9 pound difference is keenly felt when lifting the bike, but is much less noticeable riding, at least on the flats. But it is still noticeable.
So, more of a weight-beef frank, I think.

Where expendable income is E, combined weight of rider, bike, and equipment is W, combined weight of rider, bike, and equipment after upgrades is U, and reasonable expenditure is R:
R<E
And
R </= E×((W-U)÷W)×20
R<E
And
R </= E×((W-U)÷W)×20

Edit: I didn't realize that many folks apparently don't have private bus companies. Around here, taking a private bus is a very popular way to get to work in the city. Lakeland can also be a great way to get to the mall or the casino.
Full disclosure: Lakeland used to have competition (DeCamp), but they went out of business after the pandemic.

I just got some fat tires and filled them with helium. Hydrogen would be lighter, but then I couldn't top them up at Party City.

Serious question here: It has been apparent and still is, based on some of the posts on this thread, that some folks will spend quite a bit of money to lose what amounts to ounces here and there to have a light bike. How do you folks who consider yourselves 'weight weinees' feel about the advent of hydraulic disc brakes? Just like that, the industry pretty much created a new standard that appears to go against the 'lighter is better' mantra that they emphasized for so many years.
Not really comparable, according to How Stuff Works "A plane like a Boeing 747 uses approximately 1 gallon (about 4 liters) of fuel every second. Over the course of a 10-hour flight, it might burn 36,000 gallons (150,000 liters). The 747 burns approximately 5 gallons of fuel per mile" Gonna guess gas costs alone on a trip really skews the trip cost on a bus vs a plane. Not to mention, buses don't have stewardesses, co-pilots, or the same pay scale for a driver vs a pilot.

Takes a little more skill but - drill twice as many holes but only half way. Same weight savings and they will still hold water. But if you reconsider after weighing that water, finishing the holes with a trim knife will be easy.

I weighed the calipers that came on the "new" bike and the Cyclones I was using. "New" (Superbe?) weighs 149 gms (front). Cyclone 156. Good. The prettier ones go on. And I get to do the oh-so-elegant drive-side seatpost route with the sweet housing curve. No markings at all on the calipers. Just like the very rusted ones on the 1st Pro. Levers are DiaComp (but I'll be using Tektros. Horrows! So I gather DiaComp made these calipers in Superbe style. Like!)

Fuel is a huge cost for airlines. The global airline industry's fuel bill this year is expected to be 32% of their expenses.
