Hmmm, not having children I'm not sure I'm in a position to comment... that said I participate in a sport perceived as dangerous (scuba diving) and in a sub branch perceived as particularly dangerous (wreck diving on rebreathers, the cliche is "one breath from death".)
As with my biking, as the years progress I've had to adjust my diving/biking to account for the fact that I have more responsibilities and tbh every dive/ride is a calculated risk where I offset the potential gains against the perceived risk. Plan, prepare, train and then do it...
That is not to say I have removed risk, just that I consider the perceived level of risk before deciding on a course of action and, if required, modify my actions to reduce the risk.
Same on the bike, hang back rather than take the dodgy overtake, stay inside the posted speed limit where possible, undertake further training, stick on a high viz waistcoat when I commute in the dark wintertime... and if anyone thinks that is boring then follow me down the A7 and I bet you wont be bored

Speaking as one who helps lead youngsters within a youth organisation I think we have an obligation to continue undertaking activities perceived as "dangerous" in a controlled and sensible manner. Young people need to see that the avoidance of all risk is 1. often not possible and 2. often not realistic if you ever want to leave the house(!) 3. Often the avoidance of fun

Giving up riding bikes teaches your children that bikes are dangerous and "good" people don't take risks. Continuing to ride but in a responsible manner teaches that risk is a fact of life and must be considered, BUT that the complete avoidance of risk can cause you to miss a lot out of life...
Our lives are not dress rehearsals, we only get one go and there is no "perfect" solution, I may cross the road tomorrow and be killed by a bus.... but if I use my head (and eyes and ears) I can make it unlikely and help ensure I am alive to go for a nice enjoyable bike ride....
Or that's the plan anyway
