I was riding home from work last Friday, in the left hand lane of a 6 lane road (Northbourne Ave for any fellow Canberrans), traveling at the speed limit, 60, with my L plate blazing away on the back of the bike. I checked my mirror and am shocked to see a Subaru badge way too close for comfort. I'd estimate that the car was about a metre from the back of the bike. Of course I was a little discomforted by this, and became even more worried when the driver started swerving back and forth within the lane. A commodore driver in the lane next to the subaru started blowing the horn, however at this point I thought it was the subaru driver. Some traffic lights changed to red ahead of me so I stopped and turned around to glare at the subaru driver, who then started pointing frantically at the commodore driver, at this stage I was unaware that the commodore driver had been the one blowing the horn, so was naturally thinking "WTF is wrong with you?". Lights turned green, got back up to 60, Subaru driver began maintaining his metre following distance again, Commodore driver started blowing his horn again. I started flashing the brake light, the suby driver didn't back off. This went on for another 30 seconds before the Subaru turned off. At the next set of red lights, the commodore driver got out and appologised if he'd worried me, but he was concerned that the driver of the Subaru was going to run me over, and was attempting to get him to back off. I said Thanks, and I was going to report the Suby to the cop shop. Unfortunately by the time I got home I'd forgotten the entire numberplate. You've got to worry about some of the people we share the road with.
