text: Gas in the surrounding area currently is sitting around $2.75. From what I know the average car can hold somewhere around 30 gallons of gas. Lets say you fill up your tank and ride until its empty and then fill it up again, and lets also say that it takes you about a week to empty your tank. So on monday you fill it up for around $82.50. Come next weeks monday you need to fill up for another $82.50. In a span of two weeks you have spent $165.00. There are about 4 weeks in a month so that will be $330.00 a month. But you dont just drive your car for a month, so for a year you will be paying roughly $3960 a year! In the new driverless cars they can take that almost $4000 and cut it down to around $2000 since with the technology in the new cars you will be stopping in at a gas station about half as many times as you would be if you were driving in one of the old cars.
