Taxi Driver Class Guide — Mine Theft Auto: Vice City

How you earn

Sit in the driver's seat of any vehicle and write /taxi <fare>: the fare for every 30 seconds, from $1 to $5,000 (/taxi 250, /taxi 2k). The meter is on.
Everybody who sits in a passenger seat pays you automatically, the moment they get in (that covers the first 30 seconds) and then every 30 seconds until they get out. /taxi shows your meter and what you've earned, /taxi 400 changes the fare (your passengers are told), and /taxi off stops it.
Get your customers. A player who isn't a taxi driver and writes /taxi (or /calltaxi) is saying "I need a taxi." Every taxi driver online is alerted with the caller's position and how far away they are. Click the message, or type /gpstrack <name>: the same live GPS the police use, with direction, distance and coordinates on your action bar (/gpstrack stop ends it). /drivers shows every taxi that is running, with its fare and how far away it is.
It adds up fast. A passenger who rides for five minutes at $250 pays you about $2,500. Your price, your route, your customers.

Your income is cash, and cash can be robbed with /rob. Bank it.
A taxi is a normal vehicle. Leave it unlocked (a locked one keeps your passengers out) and anybody can take it the moment you step out (+1★ for them), and a Car Jacker can break a lock.
A passenger who can't afford the fare is let out, and you're told.
The meter switches itself off if you leave the driver's seat for 5 seconds, and a server restart switches every meter off.
At 4–5★ the police can pull your vehicle over like any other.

Pick a vehicle with seats: a Sedan seats you and one passenger, a Delivery Van you and three. A motorcycle carries nobody.
Park where people gather: spawn, the banks, the Parachute NPC, the casino.
Set a fair fare. A passenger just gets out of an expensive taxi, so check /drivers before you set your price.
Bank your cash after every shift.

Write /taxi <fare> in a driver's seat to start the meter. Everybody else writes /taxi to call one.

Taxi Drivers: sit in the driver's seat of any vehicle and start the meter. The fare is for every 30 seconds ($1 to $5,000), and passengers pay you automatically. Everybody else: write /taxi to call a taxi. Every taxi driver online is alerted with your position. /taxi off stops the meter.
Lists every taxi that is running, with its fare and how far away it is.
Puts a live GPS arrow to a player on your action bar. Police follow suspects with it, and Taxi Drivers follow the customers who called a taxi.
The same as /taxi for a player who needs a ride: it alerts every taxi driver online.

You can change class at the Hospital NPC. See where to go for the price and cooldown.
