A taxi driver makes money from the payment that his customer gives to him. More customers means more money for him and that is why, you need to be industrious in this line of work. You don't get paid if you can't send customers to their destination. You need to take care of them while they are on your taxi and you don't want them to get annoyed or they won't be riding on your taxi anymore. That would kill your business and might put you in bankruptcy. A taxi driver must meet the boundary each time, he takes the taxi for a ride or he can't pay the taxi operator. If he can't do that then the taxi driver won't have any taxi to drive next time. Drive the taxi as fast as you can till you reach the destination, but you need to practice safety precaution to protect the customer from harm. Don't forget to stop whenever the traffic sign is red or you would lose some points. As much as you like to get to the finish line as fast as you can, you should also consider the health of your customer or you might not get paid at all and lose the game. You can use the money to upgrade your taxi.
