Quit using Strava for commuting. Before that earned some weird local legends. Mostly one mile segments on flat roads that are pretty boring.
Now I use Strava for mapping my recreational rides. Most of them. Like to look at the maps. And if anybody else shares, their nearby rides too.
As to tracking I use a cheap bike computer and spreadsheet. Strava always reports more miles than the bike computer. I measure the wheel once a year or so. Trust my bike computer most of the time.
