I see it all the time Ted..... That looked like it was just before the Epping Tunnel, which has a toll. Obviously a panic because they didn't want to pay the toll or some such stupidity, so for the sake of a few bucks, this absolute moron endangers not just themselves, but many others.
I've been a courier, trucker, even drove garbage trucks and still ride motorcycles for commuting and recreation, and the advent of the mobile phone and SMS has been instrumental in causing more accidents than any other issue IMO.
This is followed a close second, and in some ways related to the speed at which some of us insist on living our lives...... There are some who believe that whoever it is on the other end of the phone can't wait until we are free to talk, or that an email can't wait.... I kid you not, before the advent of the iPad, I used to see guys in the city driving with a laptop on their lap doing emails whilst driving.
Slow the f@&k down and consider others for a change...... Have some courtesy and let the other guy in........ Because no matter how important you think it is, it's not worth someone's life, or limb....
So if you see someone doing something really stupid, tell them so in a nice manner, because the bloody coppers won't, they're too busy talking non hands free and texting whilst driving because they believe they're above the law.
Woops, that was a bit of a rant
