Whoops! So, here's the scene. A car pulls out in front of another car. The guy blares his horn at the offender. That guy is so caught off guard he crashes into a streetlight. OH NO!

 

So, clearly there's a car turning and the guy who pulls out wasn't really looking or paying attention to the other car that's behind it. He just pulls out forcing the other guy to slow down and honk at him.

That guy is probably so freaked out that he loses control of the car and just plows into a streetlight.
