Why don't drivers use indicators?

A new national survey reveals that 57% of American drivers admit they don’t use their turn signal when changing lanes, but what is most startling are the excuses drivers gave.

According to Response Insurance, a national car insurer, 42% of those drivers say they don’t have enough time, 23% admit they are just plain “lazy,” 17% don’t signal because when they do, they forget to turn it off, 12% admit they are changing lanes too frequently to bother, 11% say it is not important, 8% say they don’t signal because other drivers don’t, and perhaps most disturbing 7% say forgoing the signal “adds excitement to driving.”
