Great to learn new areas and a quick source of money. The faster you reach the destination that the customer wants to go to, the higher the chances of you getting a speed bonus which gives more money. For every 5 fares done consecutively, a 5-in-a-row bonus is rewarded. To get these, it's important to focus on keeping your car intact rather than collecting the speed bonus. If you're going for consecutive fares, it's also important to have enough fat so that you don't die from exhaustion.
If your Taxi gets damaged, the game prompts you to go and fix it at a Pay-N-Spray shop; this is highly recommendable, as the repair only costs you $100, which is easily covered by the ever increasing 5-in-a-row bonus.
Use the nitro taxi cheat code so that you can go to places faster.
- Finish 50 fares (total, not necessarily consecutive) to get nitrous boosters in all Taxis and Cabbies. In additon to the ability for your taxi to jump when you hit the horn button.
