text: Secondly, cars are a huge source of air pollution to our planet. If we don't limit our car usage, who knows what will happen to our ozone layer and ecosystem. According to Source 2, countries like Paris have already noticed this and are taking the initiative to prevent further pollution. "After days of near-record pollution, Paris enforced a partial driving ban to clear the air of the global city. On Monday motorists with even-numbered license plates were ordered to leave their cars at home or suffer a 22-euro fine ($31). The same would apply to odd-numbered plates the following day." Within days Paris had already observed a difference in their air quality and a sharp decrease in smog. "Congestion was down 60% in the capital of France, after five-days of intensifying smog . . .".    The driverless cars would be something people would like to have but they may not be very safe. There is the same amount of negative aspects as well as positive aspects of the cars. I am mostly against the the development of the driverless cars.
