Streamlining helps the cars reduce friction, which makes them have better gas mileage and be able to move faster.
Examples of the streamlined shapes in day to day life include airplanes, cars, boats, ships, cycling hats and swimming costumes.
Fish, seal, sharks, dolphins, and so on, are all streamlined so less energy is wasted swimming through the water. Space rockets, cars (especially racing cars) are streamlined to use less fuel and have less drag holding them back by air friction.

There are many different streamlines object. The streamlined object is the object that air hits it least. Any object that is pointy or Begin with small part to a big part this is streamlined object.
pie
Cars with good aerodynamics.
Their shape and aerodynamic efficiency makes them streamlined.
aircrafts and fast cars are streamlined so that the air flows over them more easily
Ferrari
They have a streamlined bonnet so that the air will be pushed over the car.
Helps improve fuel mileage.
the way they were desinged by the builders
race cars are streamlined so that they can try to be as quick as possible and also so that they can acheive the highest speeds that they can. i mean they are streamlined because they want to be quick and overall they wont to win the race :)
to be able to get through water as easily as possible, the same way that planes and fast cars have to be streamlined.
less wind resistance, better fuel mileage
The most common features in modern cars that help to reduce air friction is the streamlined design of the bumpers and spoilers. The streamlined shape of fast cars also helps to reduce drag.
Lorrys air not streamlined beacuse there is no where for the air to go when it hits the truck. But some lorries are streamlined but not to the exstent of cars like the renault k-80 which has curves to direct the airflow
