Hi Goal,
Unfortunately falls happen. Earlier this week I went over when I got caught in a wheel rut that I couldn’t see when riding home at night. One other recent fall was when I had to come to a stop before crossing a road, rather than unclip I decided that I’d be super-cool

and remain clipped-in and grab hold of a pole. Well I missed the pole and over I go.
Perhaps the best fall I’ve personally seen was when I was doing the Brisbane to Gold Coast Challenge last year. Up ahead of me there was a group of 3 riders, two guys on the outside and a girl in the middle all happily chatting away. They were all clad in lycra and appeared to be on really nice bikes. I’m just cruising along 20 meters back and as they came up to a set of lights they all unclip except one of the guys, he tumbles onto the girl who then tumbles onto the other guy, all of this appearing to happen in slow-motion. The final result was a tangle of bicycles and various rider appendages poking out at strange angles. Only effect was a few minor bruises, some minor scratches and massive embarrassment

.
The road authorities here seem to love painting lines, symbols and speed limits onto the road surface on wet days these are massively slippery and trying to turn while riding over them is almost guaranteed to cause a tumble.
It’s really only a matter of practice and accepting that falls happen.
