Evolution of cars technology

When Ford created the model A it had no technology and they had to crank start them. Since then technology has increased dramatically first was key start so there was no more crank starting needed. Then came air conditioning, radio, GPS, to tv's in cars, and now being able to press a button and your car starts. The technology has also changed how engines ran. Cars used to be all engine and what you see is what you got. Now they can plug a computer in your car and it will double your horsepower and double your torque. It's crazy a simple computer controls your car/truck.
