> So, what's happened multiple times is that the 10 minute estimate ends up staying at "10 minutes" for 5-10 minutes straight and 15-20 minutes after I booked, the driver shows up.

I have noticed this over the weekend as well. Got an estimate of 15 minutes (which is much more than usual). After 7 minutes the car was still 15 minutes away and it was even further! Had to cancel, got charged, used my own car as I was already late.

This has happened in Vilnius. What fascinates me most is that how a single shift in software behaviour has an instant impact on people lives around the world. Makes me think what economical impact would happen if it unexpectedly stopped working (or worse behaving as expected).
