Uber currently has a $15 minimum total fee in DC. They charge a $7 fare (the "flag drop" rate) and then $3.25 a mile after that. The proposed amendment, if I've read these articles correctly, would have raised the "flag drop" rate to $15 and then any mileage charges would have been on top of that. For comparison, the flag drop rate for taxis is currently (and would have remained) $3.
