I've only run a red light once so far. Needless to say, I almost crapped my pants
I was coming home from seeing friends in Nottingham. I was almost home and it was about 2am. I wasn't speeding, didn't have any lights out, or doing anything wrong. That didn't stop me being paranoid as hell when two police video vans pulled out of no-where and started following me though. I'd only been driving for a month and even the thought of being pulled over scared me.
They followed me for about half a mile and then turned off. For that half a mile I couldn't help but almost stare into my rear-view mirror. Just as they turned off, my attention turned back to the road and I sailed straight through a red light and onto a dual carriageway. Thankfully, being 2am, there was no traffic.
The thought of a fine etc caused me enough anxiety to drive back there the next day and check there were no red light cameras
I think it's good for a few bad (but not dangerous) things to happen to you when you start driving. It kinda knocks you into shape. I always like to practice stuff when I want to rather than when I have to. For example: the first time it snowed since I passed my test, I went out in it at about midnight and headed for a car park so I could learn to control the car better in the snow. Better learning then than in heavy traffic when I don't have a choice.
