I remember when I first started out on the road. I was so scared of crashing, I was only concentrating on the car in front of me. Glaring at those brake lights should they decide to come on.
A year and a half later. I'm scanning the entire road, pavements, too. Looking out for indicators that flash. Looking out for kids who think it's funny to run out in front of you. (If they had done that a year ago, I can safely say that at least one of us would have been 6 foot under now. But thanks to experience, I let off the throttle and cowered the brake should they run out - Bloody good job I did that)
Close calls are all part of roadcraft. You can't expect to be a perfect rider as soon as Day 1 is over. I consider myself to be a much better rider than what I was, but by no means am I a fully aware and experienced rider. That takes decades of riding. Even those who are extremely experienced can have close calls. Different situations call for different observations.
Get yourself a copy of "Motorcycle Roadcraft" (Link Here) Scan through that a few times.
If you still want more training, the local constabulary occasionally run a "BikeSafe" scheme (Which costs somewhere around £45 for a weekend.) I haven't personally attended one, but I have a few friends who have and they said that there are so many more things to learn that they hadn't even thought about. The scheme is undertaken by a couple of Police Motorcyclists, who, as you know, go through intensely difficult training and a whole range of examinations to even be considered. Their standards of riding are intensely high.
Right, enough of the rambling. Hope you have fun rides out on the roads, but most of all, be safe.
