It can be, but isn’t the most realistic starting point for someone out of shape to go from being overweight and driving already for 45 minutes (without traffic) to cycling 40-50 miles each way.. also people have kids to drop off/pick up, errands to run, etc. don’t think in the US its reasonable to say “the vast majority do”. Most American cities are not known for their bike friendliness..

The reverse can also be true, I've done 2x10km commutes for much of my adult working life and even if you wanted to push it to the point of sweating and having to take a shower, traffic usually foils the plan so you're confined to a more or less leisurely pace (ofc this can be 13 km/h or 22 km/h) and yet... I don't think it helped me a lot. It's just not a lot of "exercise", even if it's 10x30min per week.

Well, I know nothing, but to me it looks like a lot of exercise. Many people are getting less in total than what you're doing just in your commute...
