That's why it's also called the FAST LANE.
It ceases to amaze me at how many people just drive where ever they want without any regard or awareness of the other drivers sharing the road with 'em. My daily drive along the 101 and into Malibu Cyn. makes me wanna pull each and every one of my hairs out one-at-a-time... and I have a lot of freakin' hair.
I've decided that the majority of drivers found their licenses as prizes in Cracker Jacks boxes because most of 'em have completely lost the skill of looking in their rearview mirrors. People despise tailgaters, but I hate people who cruise in the passing lane or those who refuse to use turnouts. Time and time again I find myself behind some douche bag going through the canyon with the death grip on their wheel crawling along as if every turn might throw 'em off the side and send 'em rolling to their doom.
Interestingly enough, someone actually had the time on their hands to put a web page together about this very subject.

It all comes down to milliseconds and gridlock...
