My general sense is that there are currently fewer Uber drivers so the supply is limited, and prices are higher. I've seen a sharp increase in the driver recruitment activities, perhaps to replace those who've been scared off by the authorities.

The last time I used Uber, ~ 7 days ago it took quite a while to get a car, ~ 30 minutes. Since then I've been using GrabTaxi, or GrabCar, which have been easier in those locations where I've needed a ride. I've gotten to know a GrabCar driver who lives in one area I frequent and I often message her first.

GrabTaxi's booking fee remains 25 baht (may now be 35 baht), which you add on to the meter reading (for an advance booking, like ordering a taxi for the next day, at an odd hour, might be 45 THB).

Edited to add: I just checked a GrabTaxi booking this AM and the booking fee is advised at 35 baht; not sure what's up with that? It was 25 baht three days ago. I guess you can add a "tip" if you encounter problems getting a taxi to bite, I've never had to do that.

Maybe more drivers have switched over to GrabCar?
