another danger is police cruisers shadowing your car at night... once they have their eyes on you and want to pull you over just to check, since they did all this work they may feel like to write some sort of warning or even a ticket to meet their daily quota just because they already pulled you over for no reason.. you can also get into an accident from the distraction of a police cruiser literally tail gating you in order to induce you to do some mistake under psychological pressure.. at 2-3 am they literally pull over every 3rd or 5th driver on the road just because it is late.
