That does not require logging. You can use local storage.

Had a neighbour in his 80, had multiple leg operations and he still used to take a daily bike ride to keep fit. Not to mention that even if bike commutes suck, they improve your mental health considerably, even if you go in the rain/cold.

And most importantly of all, those who can take the bike cover those who can’t. So please enjoy your car ride, but take the bike when you can.
