Need help with Forza Horizon 3.

Hey Mates, here is some helpful stuff for y’all in forza horizon 3, go to Surfer’s Paradise festival hub and try to do this, go to settings in the pause menu and select difficulty and put shifting on manual, then exit out of the pause menu and go 320 Kilometres in the Lamborghini Centenario through a speed camera from Surfer’s Paradise to Byron Bay speed camera next to the dirt road to the Byron Bay festival hub and tell me what speed you hit if you didn’t hit 320 Kilometres through it, it is better than nothing.
