Even Splitting Lanes with Stopped Cars Is Dangerous with Stupid Drivers [Video]
The video shows that even when the traffic has come to a halt, crashes can occur if some driver decides to move without checking with his or her mirrors. Signaling this intention prior to steering either way could help other road users notice that he or she plans to move and subsequently slow down and give way... but turn signals are there for nothing, in this case.
The outcome of this meeting between a reckless, ignorant driver and an unsuspecting motorcycle rider are easy to foresee: new fairings for the bike. And that one was really easy!
