Probably depends on the part of the world you are driving in. It seems 
fairly common around here, driver signals a lane change, and forgets to 
turn off the blinker. I try to hold the turn signal lever far enough 
travelto get the signal, but short of the detent (you can fairly easy do 
that on the Fords). But once in a while I miss it for a mile or 2, and 
feel bad about it. Locally we have an intersection that is notorious. 
There is a sweeping right turn on a "Y" branch, 800' to a 4 way stop 
intersection, where many people turn right, and from that new direction 
road lots of people are turning left with a  few going straight.  From 
the "Y", the turn isn't sharp enough to cancel the turn signal, at the 
stop sign, the on coming from the right think you are going to turn, and 
then they enter the intersection, you go straight, and there is a 
frequent fender bender. The warning sign says "Check your turn signal", 
but there are still benders. ~)

I would prefer brighter, better located indicator lights, but then again 
how many drivers scan the instrument panel.
