Once Daylight Savings ends in a few weeks, it will be too dark to ride in the evening when those who aren't retired get out of work, and I no longer ride solo during the weekdays after being clipped by a hit and run driver a few years ago (he was caught.) My outdoor rides are pretty much restricted to the weekends.
However, some of those in the riding group I usually ride with in the evenings are facing the same darkness dilemma, so we are organizing Zwift meetups so we can still ride together, albeit in the virtual sense. It's a great motivator. Most rides are configured so that everyone stays together regardless of watts/kg output, but now and then we'll have an "open" ride that can get a bit competitive in the KOMs and sprint zones.
