According to Google co-founder Sergey Brin in the passage, "The cars he forsees would use half the fuel of today's taxis and offer far more flexibility than a bus." Using only half the fuel of today's taxis would have a huge environmental impact for the better. Less fuel would be used and the fuel that is used will be able to go a longer way. With constant searches for new places to find fuel from drilling and fracking to importing, being able to stretch the fuel has more positive aspects than one. Harmful fumes given off would be reduced if fuel was cut in half and also the demand would decrease, making the needed supply decrese as well. This could greatly reduce the use of fuel extraction methods that are harmful to the environment. Also, less fuel needed would help to prolong the far future when fuel might be at risk of being depleted, making development of driverless cars would have a positive impact on the environment.
