I live in metro Melbourne and rarely drive in regional areas.
Today, I was driving on the Hume Freeway, and the rain was significant at times. Even though I felt it is quite unsafe to drive at the normal speed (110km/h), most drivers seemed to care less. I felt that I might lose grip. I ended up driving around 95-100km/h on the left lane to see vehicles piling behind me before overtaking.
What would you do in these conditions?
Its not the speed, but the spacing between cars that should matter.
