That jogger is a fucking idiot, never ever run on a road with your back to traffic, run on other side and face cars coming at you so you can get the fuck out of the way in event of an accident, if it happens behind your dumb ass, you are fucking dead.
Edit: Also, why the fuck are you linking to reddit?????
It's not just the softness of the material.... Sidewalks have lots of undulations and uneven angles every time you cross a driveway or a junction. Also gaps and cracks
Jogging 2km on a sidwalk is fine
Running at a serious speed over 10k on an uneven, hard surface like sidewalk is a high chance of injury
On the other side of the Atlantic, any human, horse, bike, motorised mobility aid etc. is justified to use the roads here (except highways unless it's an emergency) even if there's a perfectly good sidewalk. Just double-checked and the only suggestion is to wear something reflective or hivis if you choose to walk in the road.
Reminder that jaywalking was invented by car companies because they kept killing people who were trying to use the shared public spaces that were roads back then
Yah, a lot of people on this site are always posting links to reddit, I would not be surprised if we find out the developer of the site works for reddit. No other reason why linking to POS reddit is allowed and not blocked in site code from that URL from being posted.
