btw, Constantinople¹ is also not the capital. Why they changed it, though, I can't say.

The suggested speed on the Autobahn is still 130 km/h. If you're going significantly faster and cause an accident, your insurance will probably consider you at fault and only cover what they're (edit: legally) obligated to.

I drive in Germany sometimes and the roads are too busy to be going very fast, my average never got much higher than 150 km/h even if you only count the fastest portions. To be fair I haven't tried crossing the country starting on a Sunday at 3 AM, you can probably go as fast as is efficient to not waste time on extra refuelling because of the car's drag.

Much of the Autobahn does have limits though :)

I think its to calculate with the likely stops you are going to take during the journey

In Portugal speed limits are treated as suggestions.

Making Poland great again?

yeah it's neat but you don't technically drive through it. You get the car on a train. Still cool though.
