Taking public transport to start your exercise is obviously counterproductive.
Driving to somewhere where loads of other people are also going to exercise is not exactly ideal.
Driving to somewhere in the middle of nowhere to go for a walk? Not only is that perfectly safe, I'm going to assert that it's BETTER than walking from your house, especially if you live in a built-up area.
AIBU? And if I'm being U - why? How am I endangering anyone by going out to the countryside by car instead of walking round my town?
