I am both.
When I retired, I became a dedicated bicyclist! Let my wife do the driving of the car. 10K km a year more or less. Then got skin cancer and after I had 3rd lump removed, I stopped cycling in daylight so bike is not getting many km use now.
Biking made me stronger than when I was 30, slimmer and hard as a rock, removed the need for using pills for too much cholesterol and high blood pressure, coming from too many hours sitting in an office. Took a lot of my time, about 5 – 8 hours 4 or 5 times a week, almost like working. With a friend who happened to be retired pro cyclist. No mountain was too high on the island or impossible to get to the top of. On-road off-road all the same. Heavy downhill bike.
Always was careful when on-paved-road, as not all car drivers are skilled driving in mountains. Motor-cyclists are much more skilled turning on narrow high roads, if not they would not last long.
I have been driving rally long time ago when Delta-EVO was a new car. Not really dangerous as roads were cleared for us. Do not remember anybody talking about pollution then.
Surely not against any of the 2 ways to get to one point from another. Drive a lot more careful when it comes to seeing cyclists on the road than I did before I started getting into mountain biking.
Think we should all be taking care of each other. And that we should try to make the world a safe place for coming generations.
About the taxing: You understand more than most.
