Sure badly built or unprioritized public transit infrastructure might suck, but busses and trains sure are amazing when prioritised, built correctly.

Many European cities combine well functioning train, bus and cycle infrastructure, which together makes it possible to go anywhere at any time for cheap.

I think it really just comes down to prioritizing to develop the infrastructure (costs money and requires political will to move away from car based infrastructure).

Also I don’t think a pod system would solve any of the problems of either cars or trains/busses and would be much more expensive…

Air conditioning is very uncommon in my country, because of the climate, so we do not have it. It is insulated quite well, but it probably also helps that there are only two outer walls, while the rest are walls separating apartments. The building is from the early 70’s, so it is not that old.

The interior walls in my European apartment are made of a thick layer of reinforced concrete I find it quite unlikely any bullets will go through…
