I personally like the relative solitude of cycling. I'll stop and jaw with people I run into along the way if I choose, but generally I really like that for a small window of my day, my time is mine and my headspace is mine.
Riding motorcycles seems to have a similar group fetish aspect to it and I never really liked group rides very much either aside from the rule of threes for offroading. Even with that, I liked that people were in range, but during the ride, I liked to ride my own ride.
I find it a lot more enjoyable to only meet my own timelines and my own goals. I ride with Strava for the convenience of tracking my own data so I can look back after the ride and get an idea for my efforts...I don't even look at it while I'm going along. If I happen to get an "achievement" during the course of my ride, it's just an amusement for me. The only achievements I'm concerned about is my own fitness progress.
