you also don’t hear about it as much because people tend to bike more in warm weather so it’s more likely for you to go long stretches of time without biking when it’s getting colder.
Off topic, but I think it's funny how cycling is viewed in different parts of the world. You look at it as a hobby that is naturally done less in the winter. For me it's just a way to get to work and I still have to work when it's cold, so obviously I'm still cycling just as much. And this is true for a lot of people, the bike rack at my job is almost as full in the winter as it is in the summer.
Can you imagine having to teach your kids about these risks, help them to deal with them and prepare them for adulthood?
That would be so much work.
