text: Since the driverless cars will have to use more energy, they will need more gas to run on. Gas prices have a grater chance of rising unexpectedly since the cars may need to run on a different fuel. If the cars do run on a different fuel, it could be harder to get than gas. Gas is already a bit expensive, just imagine if driverless cars do became a big thing? The fuel for driverless cars may be regualr gas that we have today or a different fuel, but either way there is a greater chance of fuel prices getting higher.
