What is the highest speed limit for cars in the world?

The highest speed limit for cars in the world is found on certain sections of the Autobahn in Germany, where there is no specific speed limit. However, in areas with speed limits, the maximum is generally around 130 km/h (81 mph). Other countries, like Italy, have speed limits up to 150 km/h (93 mph) on some highways. It's important to note that these limits can vary widely depending on the region and road conditions.
