Or make motorcycles more popular ;)

We don’t have such problems in Austria. We also don’t have 40 degrees but I dare say it’s not inherent of trains.

Which benefits does it grant you?

Here on the Austrian countryside next to the mountains its not reaching 20 degrees at night

I don’t but my house is isolated. Windows open in the night, closed during daytime. Works perfectly.

I prefer Tuta for very private stuff (medical etc). But I’m mainly using purelymail since it costs 5€ a year. It’s in the USA but still good enough.

It really does track (you), which is why I’m abandoning my >20 y/o gmail address
