German autobahns

German Autobahns are like really big roads where cars and trucks can drive super fast! There are no speed limits so some people can drive really, really fast! It's kind of like a big playground for cars. But just like at a playground, everyone needs to be careful and follow the rules so they don't crash into each other. Fun fact, did you know that the first German autobahn was built way back in 1921? They have been getting bigger and better ever since!
