This one should be interesting mostly because we currently don't know how fast vehicles go in the game. We'll know if more radar signs are added, while it remains to be seen whether you'll need to drive at regular speed or use your various boost options to clock a speed over 25. What does stand to reason is that radar signs won't be added just anywhere. You'll probably have to be on clearly marked roads in the game, but we'll just have to wait and see on this one.
