Just a heads up every one, I was out riding today in south west of Sydney when I noticed a Black Maserati behind me, similar to the picture above, as I was turning right at a light, I noticed him speed up very quickly behind me and back off, this concerned me, and kept an eye out on him. About 5 seconds later, I suddenly hear the sound of his engine increase in RPM, I look in my right side mirror to suddenly see this dingle berry starting to overtake me in my lane, I guesstimate that he was at least a foot away from me on my right hand side. Fortunately I took decisive action, whilst he was over taking me, I moved farther into the left side of the lane and slowed down in preparation and kept maximum distance, now at first I thought this guy was being a typical turd, I started to think, what the hell is he doing?? ill have a vocal word at the lights with him, this is when it started going bad, to worse. He began to start to violently hit the brakes, at first I thought he couldn't drive, but it started to become apparent he was attempting to match my speed and get me to rear end him, how ever, I was 10 steps ahead, so no matter what he did, I was well behind him, it quickly dawned on me that this guy was trying to hurt me, I decided that this could quickly get out of hand, he may have a weapon for all I knew. So I quickly pulled off the side of the road and did a safe double back, he was still driving slow, I rode for several minutes to another suburb, pulled over, and spent a good twenty minutes trying to get the adrenalin out of me. Moral of the story is, A) If you see a Maserati in Sydney (sorry I couldn't get a license plate number) stay well clear of it, some people do not value human life, stay clear of them, do not get into altercations with them C) invest in at least two helmet cam's one for the helmet, and one for the rear of bike, clear video evidence is hard to dismiss, which I am soon to do. Non the less, please ride safely, and keep an eye out.
