Yet another poster to whom English is a foreign language. I have never said in any of my posts that I like or dislike the poster. How did we learn? By cycling, by experimenting, by observation and by making mistakes and that is the only way to do it..
Take the posts where people post maps of roundabouts and ask how to negotiate them. If I posted a map of the A57/M57 roundabout, how could you or anyone else who has no knowledge of the area help me? You do not know the terrain, road surface and camber, traffic flow or density.
"Should I tell the police?" posts - you have spent time editing your video, loading it onto youtube and posting on a forum; if I was so upset then I would be straight round to the nearest police station but you need peer approval and sympathy - why?
Close overtakes - they are always a one-off and cannot be replicated. If you cycle a regular route then you should learn it much in the same way as an F1 driver learns a circuit and this includes pot holes, trafic light sequences, daily traffic flow patterns. If you are aware of the 'danger' points then take extra care.
Beating your best time - why bother? Eventually you will reach an optimum time window - for my bypass route it is between 77 and 80 minutes. I have done it in 75 minutes, 2 seconds and will break the 75 minute barrier one day when conditions are perfect and not before.
So just go out and ride your bike - the best teacher that you can have is your own experience.
It appears English is as much an alien language to yourself.
I used to cycle the same 18
1/2 mile route, 5 times a week for just short of a year. First time it was done, as a commute, took 78 minutes. 33 minutes slower than my previous best. Same route into Leeds city centre, only I stopped on the commute in the centre. Same road has had more lights put in place, but its also been made faster at points. I still cycle the same route & I will never claim to know it like an F1 driver. The two are not comparable. Closed circuit racing versus open road.The closed circuit will also mean that most driving round will know exactly where to brake, accelerate & turn. The closed circuit will usually have people who will inform you of such minor things as faster traffic behind, danger on the track in front of you. Open roads lack these minor! but important features. Closed circuits seldom seem to have cars going round when work is taking place. Open roads do. And we have to hope that those around us are aware of the speed they are doing in relation to others.
Circuits normally have all the traffic running in the same direction, turning at the same place, time after time. Year in year out.
The closest I would come to calling anything a regular danger(built in) on an F1 circuit is the manhole cover at Monaco. There for over 50 years & still not been fixed.
You can learn a road easy enough, but when changes are made to that road, you have to re-learn it. Each & every time there is a change made to it.
Not everyone who posts on you tube does so for peer approval. They are simply asking about something they are uncertain about. A major incident to them may be nothing to you or vice versa. Regular occurrence on the trip home on an elevated section of road, 180 foot drop, was with a particular companies lorries. Slowly be squeezed over to the right, as they realised what I knew & they should have, was that they were in the wrong lane. Only the video tape being played back in their local office convinced them that what I was saying was true.
Experience is the best teacher, but it can teach more than one way.
