It seems people are never thinking what happens if he is getting old. Good luck when you can still ride a bike when you are 70s and in the snow.
I did that. Running, cycling, walking, etc. Substantially more walking than 5 minutes a day, too...

...and my right knee became unfixable trash somewhere between 45 and 50 (a variety of ailments, possibly exacerbated by a ~2001 injury.)
You really think, that we people who do drive bicycles, do not think about cold and rain? We are the first to notice it first hand. So we do think about it, as we have to regulary deal with it.
The solution is adequate clothing.
But yes, I also own a car as I do not live somewhere with good public transport system. And I do know people who ride a bike in their 70s, but I am aware, that there will likely come a time, when I will be indeed too old for riding in the winter. But chances are, that by then I am also so fragile, that I might be too old for save driving also. Hopefully self driving is ready by then.
Although it's bizarre because in the US 70-year-olds seem incredibly frail compared to 70-year-olds anywhere else.
The elderly can only drive safely under ideal conditions: sun high, not on the horizon, not at night, in clear weather where nobody is using their headlights.
One of the reasons I stopped driving 20 years ago (~30) was because I have this problem. Made night driving much more stressful.
There are also electric adult tricycles, etc.
