Just heard this from a taxi driver - I don't have any other sources of info yet, but according to him, the government is planning to make fares standard across companies, and abolish all the surcharges except the midnight one.
Furthermore, there will only be one color of taxis, instead of multiple taxis.
Fares will start at $4 instead of the varying fares now..
The driver I spoke to seems to like the new system, and it makes it more predictable for him. I for one, look forward to this too.
This system is slated to be up by August this year..
