Both noses will be running all the time, but just as fast as the noses of Albert Einstein.

You can just teleport 7 inches backwards after lunch. As the contents of your stomach isn't you, it will stay inert and fall to the floor. You can eat all you want if you don't have to digest it.

Just remember to stand up beforehand or you'll end up intermingled with your chair having chewed up cheeseburger all over your lap.

The original question also doesn't state that gravity attracts everything but oysters or that Albert Einstein has two runny noses. But that's how it is. These are just the basic rules of the fantasy pill world. Everybody knows that (at least I thought so).

Only if you are thinner than 7" minus the thickness of the door. Otherwise, you would teleport right into the door, which (I assume) might be quite painful.

Usually bodies are more than 7 inches wide, so you wouldn't end up naked, but with a t-shirt somewhere inside your body. So if it works like that, I'd advise you not to choose that pill. That is, unless you're an oyster.

In order to do that I'd have to take 💊 № 1 though, so I'd be able to communicate with people who are sℏellfish.

In a world where some people can control toasters with their mind, free gravel disappears as soon as you put a price tag on it. I'm sorry if you don't like that, but I don't make the rules.

In Germany in comparison the chances to die in any traffic accident (car or no car) is 1 in 351. So year. Pretty much safer.

TIL There's a category in the German death statistics named "Resulting from the insertion of a foreign object into a natural body opening." And I'm only mildly disturbed. That killed 775 People in 2023 btw.

If the average bus is 8 years old, that means that buses are replaced approximately after 16 years. According to this source, the average bus in New Zealand is more like 16 years old, so they're actually running for 32 years 😱

For a reasonably sized transport association it will be outright impossible to electrify an entire fleet at once:

1. Where do you get all the buses? For Hamburg alone, you'd need to buy 2600 new vehicles, which would be half of all buses sold in all of Germany in a year.
2. Where do you park those 2600 new vehicles until you've sold the old ones? For some transition period you'd have twice the number of vehicles while at the same time...
3. You'd need to overhaul all your bus depots at once, which adds to the parking problems. In Hamburg we have more than a dozen bus depots, where do you find all the construction workers to upgrade them all at the same time? Where do you get all the architects, planners etc?
4. You'd need to get a lot of electricity to your depots in a short period of time. Your local power company might be able to build a new substation for one depot a year, but 10? Probably not.
5. Where do you educate hundreds of mechanics on the new technology? And who's maintaining your buses while all your mechanics are at the training?

You don't need too much infrastructure to start transitioning: You can add charging infrastructure to on one or two terminal stops, upgrade one bus depot, educate 10% of your mechanics and start by upgrading all the lines going to these terminal stop. In the next year you upgrade the next terminals, the next depot and train another 10% of your mechanics. After a decade you're fully electric without a big hassle.

Busses are replaced regularly anyway. An average bus in Germany for example is 8 years old, so 6-7% of all busses are replaced every year. Just buy electric busses when replacing the old ones instead of throwing out perfectly new combustion engine models. That's also more environmentally friendly, as a large part of its lifecycle pollution happens during the construction of a vehicle.

The other question is obviously highly dependent on the city (size, density, geology etc.) and the type of transit you're building (underground vs overground, separate rails vs. tram on streets etc). As a current example Hamburg is building a new subway line that'll go through the entire city (25km, 24 Stations, almost completely underground) is estimated to cost 15 billion €. So, depending on how mucch your city needs it could be anywhere between 10 and 100bn for a subway net. However, the national accounting will benefit 1.28€ for every 1.00€ that's spent, due to savings in travel times, fuel, cost for accidents and road maintenance, freed up real estate in the city etc. according to the calculations.
