But even if you drive the car into the ground there is still an associated cost per year as a result of buying the vehicle.

Is that on new accounts too?

Wunderground was awesome until IBM bought it

Votes being public has made it possible to learn a bit about how people interact with posts. I’ve always used the downvote sparingly and I think that is how most people operate, downvoting only what doesn’t contribute to discussion and upvoting what I agree with. But it seems a minority downvote very frequently. There are some accounts that downvote the vast majority of posts in certain communities. Sometimes these accounts have zero posts and comments. Which is pretty odd - disagreeing with so much while never sharing your opinion.

You might be able to find something useful in one of the journals for transportation or preventative medicine. Using search terms such as ‘active travel’ and ‘modal share’ might help. You could also think about distinguishing between health state life expectancy and life expectancy.

Maybe not exactly what you’re looking for but you could also look at examples of cost benefit analyses that have been calculated in the UK, where savings to the NHS are predicted in terms of increased modal share of active travel.
