When people do the stupidest things, make u do an emergency stop, and then when u beep at them, just look blindly ahead of you like it never happened, on a 30 minute drive i almost crashed about 3 times cos of these fools!!! :| :| :| It takes the joy out of driving! The problem stems from ignorant shits being shits and not being courteous and letting people out of junctions! Or not using their side mirrors to change lanes! Or not letting people in when lanes merge! :|
