You Don't Use Your Turn Signal

Of course, though, if you use it the bulb may burn out someday. To fix the problem then you can either sell the car (recommended) or buy a new bulb which would cost the price of a bottle of Jack Daniels (not recommended). Which would give you more happiness, having a car or a bottle of Jack Daniels? The answer would differ if you're a teetotaler or an alcoholic.
You're driving in the passing lane on the interstate and want to move to the travel lane. You drive one-third into the other lane, flick your signal once and continue into the lane. Don't you think I already know that you're changing lanes? At this point save the bulb as your signal is totally useless or you've already had an accident.
