Answer to Sub-question

How will the future change in the future?

In the future, cars will be forced to march to the dictation of global warming, and the supplies left on Earth. With climate changing getting to be more of a serious problem than ever, cars will become smarter in order adapt to the environment, and to adapt to running on different fuels. Though it is sad, we do not have an unlimited supply of crude oil, nor can we spend it extravagantly. We need be more conscious of our dwindling supply and learn to rely on other sources of fuel, such as hybrid powered cars, or compressed air.
In terms of safety and security, it is the accidents on the road that we need to prevent, there is no solution to stop drink driving, there’s no solution to stop speeding. GSP in cars, to locate missing cars, ESP to stabilise cars, signal beams to signal the distance between cars and auto pilot buttons. These advances serve only for convenience, and to give drivers an easier time on the road.
Absurd notions of flying cars can be forgotten, we are doing more damage than good by having flying cars.
Due to the weather, darker colour cars will be extinct. Due petrol prices, cars will shrink, because the car that holds five, seats only one. Say goodbye to retractable roofs, to sport cars. The car of the future is not made to please the demographic but to adapt to the future changes in the environment.
