  2. The cars through time have changed style as in, on the old car, the lights and the wheels are sticking out and now the cars are lower and there are better engines for speed. Changes between cars Air-conditioning was introduced to cars in 1940. This invention made cars a lot more comfortable, especially on really hot days. At first, the air-conditioning was a little bit awkward. To turn the air-conditioner off, the driver had to stop the car, get out and disconnect a tube located under the bonnet. When the car radio was created, The car radio did not come with the car, it had to be bought separately. Where as now days nearly every car has a car radio. This invention was created by Paul Galvin.

Before the introduction of bicycle chain pedals the only way to get the bike to go faster was by making the front wheel ( with the pedals) bigger, as one revolution of a bigger wheel will cover more ground than one revolution of a smaller wheel. Now days bicycles are often made out of carbon fibre which makes them lighter
