such drivers are 'CURSE MAGNET' from other road users 
i remember a friend from college - he had an old Ford Zephyr Fintail, used to drive at 40kph in right most track, across every road in city, anyone blinking or honking he click indicator stalk for right turn as if going for turn,. after other driver make quick move from left to pass over, he reset the turn signal stalk to continue straight. he was curse magnet from all of the gang.
later in US at school his learning permit got cancelled twice in 1 academic year, for 'not observing' right of way. Now in his early 50's he do that randomly for fun., (old habits die hard)
