This is the first time I've posted this but Castiel you are talking crap.
Come and commute 1 day in my cleats and see the problems I have to face daily here in Stoke.
At least once a week some idiot will left hook me, this means a driver puts his foot down to get past and then immediately turns left - and no, my experience hasn't stopped me from hitting them.
Perhaps you would now say that since the driver didn't hit me then he must have judged it right?
After 1 year of commuting I have now had to change my attitude when I cycle and the simple rule I go by is 'I don't belong on the road'.
If I see a motorist at the junction of a side street (left or right) I now make the presumption it is their right to pull straight out on me even if I'm doing 30 mph.
if I see a motorist turning right in front of me it is their right of way and I'm expected to slow down if they just go.
It's an awful attitude to have but it's keeping me safe knowing I have no rights as a cyclist.
HOWEVER, no amount of experience can ever make me judge a car that speeds past me and suddenly turns in on me, if I stop/start for every car that speeds past me I won't get very far.
And OP, I agree that weekend cyclists may be a fad but some of us do it daily to commute to work.
Mame will back me up when I say that parking at the place I work is next to impossible and even if I could I am around 15 minutes quicker on my bike.
