There's a bug with bicycles when pressing ctrl twice or a few times once you reach the ground to jump alot higher than possible , this can be very annoying and infact counts as a bug abuse on cops when the player is wanted (especially if there's no permission to kill that suspect atleast). They have an ability to easily jump on rooftops and avoid cops. I know i'm not the one who decides what rules are there gonna be but i'm suggesting this and hopefully someone else could agree that this is a bug abuse.
