how about adding the police
flashing lights and sounding their siren just to get back to the sation to clock off
speeding just because the guy infront is and they feel the need to catch them up so that they can tell them that they were speeding
the inability to stop when they see people parked on double yellow lines at the traffic lights at the bottom of willows lane with the hazzard lights going while they get out the car to talk to their friends
using their radio while driving ,if we arnt in control of a vehicle when using a mobile phone how can they be in control with one hand on the radio
