Streamlining helps the cars reduce friction, which makes them have better gas mileage and be able to move faster.
Airplanes have streamlined shapes to reduce drag and improve aerodynamics. Fish have streamlined bodies to move efficiently through water. Cars often incorporate streamlined designs to enhance fuel efficiency and reduce wind resistance. Speedboats are built with streamlined hulls to glide smoothly through water. Bullet trains have streamlined profiles to decrease air resistance and achieve high speeds.
Objects that are designed for movement through a fluid medium, such as airplanes, cars, boats, and even underwater robots, need to be streamlined. Streamlining reduces drag, making it easier for these objects to move efficiently and swiftly through the air or water.
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.

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.
the way they were desinged by the builders
Helps improve fuel mileage.
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
