sadly times have changed, far more pervs and far more traffic, which equates too far more idiots on the roads,its not about the age, its more about being self aware on the roads and treating all drivers as if they havnt seen you, so take more precautions,ive cycled since i was 10yrs, im now 54, and been knocked off 6 times luckily nothing serious, but now im alot more aware of where i cycle and where i position myself on the road,it only takes a near miss to put some people off cycling on the roads, my misses doesnt like it for that reason,i think ita all down to the individual, wether or not they are confident in their abilities on the road, it will never be a 100% safe, but you can minimise the risks, like on busy roads instead of waiting in the middle of the road to make a right turn, wait at the side and wait for a gap in the traffic.
