I can confirm that, Yes, trips will automatically end after 4 hours to prevent driver fraud. (It seems some drivers created fake accounts with stolen credit cards and drove around for hours, or so I was told.) So it shouldn't have happened but it looks like it did, lol. There's a metaphor for life.Doesn't Uber automatically end trips after 4 hours now? I've also heard 12 hours, but either way, I don't think that is what could have happened.
