I was driving to work today and a R3 with an L plate pulls up next to me at the lights. It was raining today so the roads was pretty wet. The lights go green and I waited a couple seconds before I drove off as I was observing the R3. The rider took off but nearly lost control of the rear wheel but managed to stay upright. I kept observing the rider and the bike. I was on the left lane and rider on the right. Rider was going straight, and was going to fast as there was a car about 100 meteres down in front of him fully stopped in traffic. The rider just kept going and at the same speed then hit the brakes on the last minute and slammed onto the rear of that car. What was this rider thinking? The rider had plenty of space and time to slow down or brake. Wet or dry, that bike woudlve still hit that car.
