Nah I’m sorry I think this is bullshit. Obviously warming up with a ball can be important for performance reasons, but in terms of injury prevention they just need to move around a bit and stay warm. No one’s stopping them from doing some quick drills while they wait.
You can dislike the waiting around for other reasons if you want, but you can’t have players standing around doing nothing, and then blaming var when they get cold
Cars are not the only way to move people around. They are, however, the worst way to move people around. Take a bus and/or train, and you’ll never have to worry about parking again.
In response, more and more of our streets can be reclaimed for pedestrians spaces, adding walking/biking paths, adding greenery, adding outdoor patios, etc, instead of it all just going to ever increasingly large and crowded parking spaces and One More Lane™
