3. Well, this does not really check out. We do take our eyes off the road, for a second. Sometimes. There are somewhat safe moments to do this and less safe ones. When several hundred meters of highway ahead are empty, the road we will travel in those seconds + some safety-cushion, and it is straight, it is somewhat safe. You are just exxagerating a bit. On a long boring ride or drive, the mind is not really occupied by the task, the eyes can still safely look at the road, ready to react with exactly one single thing to anything unforeseen: appyling the brakes.
I like motorcycles, therefore i want to point them out. In the EU, they are a luxury fun vehicle for the most part. Still it is amazing how they are thoroughly ignored. The german publicly funded media as per Rundfunkstaatsvertrag is supposed to help people make up their own mind, however the fact that a sub300kg vehicle is probably more efficient in single person transport than a 1200+kg one is mostly held under wraps, motorcycles are only mentioned when it is about noise and speed. The climate movement, fridays for future, also does not seem to think about this at all. Sure safety is a point, i would have counterpoints, as in it being an infinite argument, a tank is also safer than a car, but however you feel about it, even people that pretend to be very radical about doing something about climate change do not even advocate for 125cc motorcycles. The propaganda is pretty effective.
