It was increased from 130km/h in the 21st century.

What's surprising/weird/hilarious is the traffic fatality rate before and after the change:

I'll let you google when that was so as not to spoil it.

It's really not, especially on a highway. Makes me sad to read about more and more speed restrictions - there is nothing wrong with those in areas there cars and pedestrians cross, but seeing a highway with a 110 (or sometimes even 80) speed limit just feels stupid. Sometimes I'm happy to live in a place with relatively modest speeding fines (also, you have to speed A LOT to loose your license over it, it's a very rare occasion).

For Americans, 120 kph is ~75mph and 140kph is ~85mph. I think there is a single road in the US with an 85 speed limit, and only some states use 75-80.
