That's when I had my accident too. I'm much more comfortable leading a group or riding solo as it's much easier to choose the level of risk when you're not also concerned about getting lost or splitting up the group by not overtaking.
Mine was also after riding about 500kms in a day on mountain roads.
I did 3 routes twice, then went off around Cambridge roads, stopped for fuel before going off to ride on the good roads around Gratham, took a brake nearby a lake and headed off home as it was getting late. I was knackered. But still wanted to take the back roads home, as it was nice and sunny. It was one of the first days when it was nice, it was boiling that day.
Well I'm assuming that the kerb wasn't straight ahead on the road, so you must have turned? Anyways you're obviously not ready to even consider your riding style is dangerous so keep your head deep in the sand.
It was nearby a dual carriageway, maybe someone in front of me changed their mind about entering it and did an illegal u turn? Idk, I got my conscious back when police were there and paramedics were loading me onto the board.
I'll upload a video later, a guy slams his brakes in front and stops on the roundabout... people can do anything. I don't know what's going through their heads when they do it.
The difference is I learned from my mistake rather than going "oh well I don't really know what happened so maybe I'll get a track bike and risk the lives of others there too".
You can still learn from a crash when you have no recollection of it. Your attitude and riding clearly ended up in a bad situation, so if you ever get on a bike again you need to change something to avoid repeating history.
I'll admit it, if it happened 2 hours before, I would probably be dead and hit whatever I tried to avoid. You say I haven't learned from it, but I learned one thing... roads in this age and day aren't worth the risk. Hence why I said, I'll go to the track and learn how to ride properly. I signed up for an event where an ex-racer was going to give tips on the cornering and you got to do a trackday for cheap. But my crash happened...
I lost a friend 2 years ago, a guy pulled out on him... his excuse was "I didn't see you..." I don't want to die that way, if I kill myself its a different story.
