I've been on Strava since it was in beta, and I've really loved the evolution and growth of the app. I can't recall seeing any "car rides" anymore, but I suspect it's both because headunits beep, auto-stop, prompt for end-of-rides, and offer instant ride summaries now, as well as Strava's ongoing efforts to eliminate the problem.

More than that though, to whatever extent fake rides exist, it just doesn't seem to be a problem for me, as I'm more interested in following people I know rather than chasing KOMs all over town. It's true I'm too old and slow to contest KOMs now anyway, so there's that, but I'm not so far down some of the leaderboards or so disconnected to local community that I wouldn't notice egregious fake rides, like a leaderboards unknown solo smoking one of the fast kids from the local race club.

I'm not even in the top 10-- top 10% maybe!-- but I know or recognize most of the people who are, so I just don't see fake rides as a big problem in my use and enjoyment of Strava. I realize that's probably a lot to do with my particular perspective and location, so I applaud Strava in trying to eliminate fakes, cheats, and mistakes, and even to integrate e-bikes into the platform.
