So me and the missus are heading to a family lunch at Rooty Hill RSL. Travelling via M4 we had a bike (+pillion) near us all the way - just another road user - who ended up taking the same turnoff as us. Bike filters through a bit of traffic and disappears. About 5 mins later we are approaching the road bridge over Rooty Hill railway station and see the same bike again two cars ahead of us with a commodore riding (excuse the pun) his ass like he's trying to give him a prostate exam. Bike flashes the brake light at commodore, and the driver reacts like a bull at a red flag. Starts really menacing the exhaust pipes in an obvious stupid aggressive display, gets half a chance and pulls along side the bike in the lane on the bridge - one lane each way, solid white line, traffic coming other way. As they approach the traffic lights on the downslope on the other side, commodore does a wide veer to the left and cuts back with the bonnet of his vehicle to T-Bone bike but stops inches short. My missus whips out the camera phone to start video - recording as they are having words, then big fat ****er jumps out of the driver seat, gets in the riders face, then smacks him (open palm) across the back of the helmet. Rider puts side stand down, turns engine off, pillion still on the back. I jump out and head towards them, I can hear kids screaming in the back seat of the commodore. As fat ****er is getting back into commodore, I tap the rider on the shoulder and tell him, no dramas we got in on vid + his number plate. Lights go green commodore goes into RSL carpark, and we pull over with the rider on nature strip after the lights. Swap numbers, send him the pics of the number plate. Rider was on a Cagiva Raptor 1000, heading to a wedding with his petite missus as pillion. Little bit shaken up, understandably, had a chat with them both calm them down, shook hands off they went. So in a scenario like this, if you are the rider and have your wife / girlfriend riding pillion, what would you do?
