People take their salaries and buy food, clothes, heating and air conditioning, cars and fuel, and plane tickets, and furniture. All of those things generate emissions in their production and/or transportation. This is why dollars is such a good proxy for co2 emissions.
Surely a person driving 18 people will emit less than each person driving themselves? I can see how dollars can be a proxy for macroeconomic stuff, for example by comparing countries, but it doesn't make much sense for comparing individual units of transport.
I don't understand why we have to do napkin maths to guess what's more polluting. There is countless research showing buses emit less than individual cars per passenger per km, self-driving or not.
And there's no reason buses can't be self-driving as well, if anything, them driving slower, on dedicated lanes and on fixed routes would make it much easier.
The very source you are providing is pretty clear to me. For cars, only hybrids and EVs are more efficient, and that is because it's comparing electric passenger cars with all buses (most of which still run on fossil fuels). There is no data for electric buses, but it's pretty intuitive to me that they would emit less per passenger kilometre than an electric car.
It would be compatible with life for longer though. A dry sauna can get to 80-100°C, steam rooms are "only" 40-50°C. And subjectively, I can bear it much longer in a typical dry sauna.
Huh, this is the first I've heard of that one. Has anyone here tried it? I assume the main appeal for those who use it is the country of origin, rather than performance?
The inner screen is definitely not as durable as the outer one. I've not tried it, but it does feel like a hard press with a fingernail will leave a mark.
There's usually some space between train coaches (I think it's called a gangway?) or at the end of a coach (a vestibule) that is separated from the seats area by doors on both sides. You can take your call there.
In London, subway cars are either completely separated and you can't travel between them, or it's just one long continuous tube, there are no vestibules. You don't get much signal underground either way, so it's rare to see people on a call.
Most trains however have a space [0] at the end of each car where you enter and exit. That space can also have a toilet, bike storage, various (locked) train controls, sometimes even a few seats [1] where you can sit if your call will be a while.
