It depends where you are at 2:30am. But really no different than 7am or 2pm – there could be a Driver around the corner from your location, or possibly over 15 minutes away. Uber might reject your ride request if there are no drivers nearby (beyond some threshold) – but generally the “Service” is available 7/24/365.
