private cars

Cars are one of the most, if not the most covenient way of getting around. People need cars for thier everyday life. Only 25% of all households in the uk do not own a car.
Most people use thier car to commute to and from work everyday. This convenience of having a car has led to 80% of males and 63% of females having a driving licence.
But having this high percentage of people using cars is unstustainable. CO2 emmisions form cars having increased by 4% from 1990 and 2006, and road traffic volume has increased by 20%
so if private cars are so unsustainable, why dont we use puplic transport?
Well, only 28% of the population use a the bus once once or more times a week. This is due to busses not being as convenient as cars, as they are quite often late, and u have to wait for them in cold and wet weather, they take a lot more time to get to your destination, and it can be a long walk to and from the bus stop.
so if not buses, how about trains?
Well tains are just to expensive during peak times, you might not be able to get a seat, and journey times are very long as you might have to catch a bus to get to and from the train station.
so instead of finding alternative wasys of comuting we should stick to driving private cars but look at ways in which we can reduce the CO2 emmisions.
Thier are changes we can do now, instead of doing nothing whilst we wait around for electric or hyprid cars to take over.
Simple ways in which we can reduce are CO2 emmisons from our car are basically driving effeciently by sticking to the speed limit, not rev the car up, keep tires pumped up to the correct level, get rid of any unnessary weight in the car. Also driving in this way will save you money as you use less petrol. I comute to uni and driving in this effiecent way i have reduced the CO2 emions from my car, and saved myself money by not using as much petrol.
