distinguish between fuel cost and revenue.
The fuel cost for a set journey must remain the same so long as the distance and fuel costs stay the same. However at the moment the 'total fuel cost' seems to increase when the profit margin is increased. Better it would be to have a display showing the cost in petrol for the driver, the payment per person, thus the total payment received by the driver and the profit he makes. The petrol price does not increase for the driver simply because he charges his passengers more!
Hi Megan, you're absolutely right. We'll look into improving this.
