I live in Germany so there are no speed limits here :D
The fastest I ever drove was 200kph... but I scared my mother to death when I did it.
Here the limit is 120 kph in the highway. Inside cities, the limit is 60 kph.
The speed limit in Ukraine on the highway is 130km/h. But of course some people allow to drive 180km/h or more depending on car they have and depending on how they are stupid and crazy.
Here the speed limit is 120km/h and the highest speed I drove was 125km/h.
in china the limits is 120km/h,but sometime speed limits is 60km/h,80km/h,100km/h,110km/h
In China ist limited in 120km/h.
