One of the first people I've actually seen playing this game that can actually drive lol. :) Wish this game was for Playstaion. Maybe in the future they'll decide to bring it to real consoles. ;)
When you're changing your road, you enter on the first lane of the road, not on the second or the third. When you've entered on the first lane, later you can switch between lanes. It's called "Driving Legislative", that you should know if you're having a driving license.
