Lately for some reason i've been out at three a.m. every day this week and i never turn my signal on. Simply because there is no one else out. Its not a big deal and im not going to get side swiped by some car that magically came out of nowhere. I'll sometimes not use it at four-way stops as well if i pull up to the sign first. Its my turn to go and i can go whichever damn way i want and i dont have to tell the guy to my left jack. He's supposed to wait until I'm out of the intersection to go ne ways.
Now having said that, if he decides to go cause he thinks im going straight and he rails into the side of me, then i will get out, beat the hell out of him, and then take my ticket for improper signaling...and probably for beating the crap out of some random guy. Oh well...you win some you lose some
