2007, so long done and dusted
It was a misty 4am, cruise control on, I hit the brakes at 100 yards and the car didn't slow.
The roundabout entry has a nasty kick about ten metres from the give way, and I elected to keep the car straight and upright rather than force it around the roundabout.
Two people almost crashed whilst we were waiting for Plod etc.
I had the headlights on dipped beam due to oncoming traffic and the mist and the Vectra C headlights are crap, (I had actually had them adjusted at the previous service because I found them so bad. The car was barely 18months old), first warning of the roundabout was the 100 yard sign.
Bottom of the car was all kinds of torn up, but I suspect that I had fractured a brake line bottoming the car on a level crossing returning from a job a couple of hours earlier. Two kerbs and a post later I can't prove that, but the ABS didn't kick in and it didn't lock up and no airbags fired.
I was the third person that week to hit the roundabout.
I remember looking at the trip computer, and whilst it is possible that I may have momentarily nodded off, but I don't think that I had, but when I looked up I happened to see the 100 yard sign.The car should have easily pulled up from that speed, but it didn't, but as the driver of said car, I was ultimately responsible for all of the above, so was technically guilty of failing to negotiate the roundabout.
Point being that in any situation, there's alot more going on than first meets the eye, but ultimately it is the driver that is responsible because you're expected to be aware of, and preempt, the possibility of what might happen if you do/don't do something.
