Software engineering in Canada in the 2000s. Most of the labs in my university ran Linux, at least in the engineering, math, and science areas of campus.
Personally I ran, depending on the year, LFS (Linux from Scratch), Slackware, or Gentoo (which still lives on that laptop today but also it hasn’t been booted or connected to a network in like 10 years).
I think there was only one lab with Windows. We also had a lab of Solaris machines but I bet those are gone now.
No idea what Law, Nursing, and other faculties in the other side of campus used.
Talking with cyclists it’s actually the opposite. It works in the sense that if someone is turning right they will get into the right lane and essentially self block a bicycle from pulling past them on the right side (if a cyclist did that they have a high likelyhood of getting hit as they are pulling into the cars blind spot… Then traffic starts moving and the right turning car just goes and suddenly there could be a bike there).
