it's because there is a space underneath the motor which allows the heat and smoke to get out quickly and without heating the car and there are also some open spaces on the hood depending on the car
Update:
If a vehicle seems to be smoking from under the bonnet (Hood), assuming that there is nothing wrong with the electrics/fuel system etc, would it be reasonable to assume without seeing the vehicle, that temperature variations can and do play a roll in what can sometimes be seen as steam appearing from cold engine compoents from a cold engine starting and warning up?
White or gray smoke coming out from under the hood of a car could be the result of a small water leak spraying water on a hot engine. A running engine is naturally hot enough to create steam when water hits it.
Make sure you have enough coolant in your radiator. The radiator is the thing in the very front of the car, the very front of the under the hood area.
There are numerous relays in the under hood fuse box. There are switches all over the vehicle.There are numerous relays in the under hood fuse box. There are switches all over the vehicle.

mine are under the hood on the passenger side firewall closest to the windshield just under the hood light. there is a black cover over them that should tell you what relay is what
i think you cant because your body isn't over heating
Under the hood, pasenger side firewall.
It should be in the front under the hood near the intake
Smoking from near a wheel points to the brake on that wheel binding. Take the car for a run, when you stop the car touch the wheel with the BACK of your hand QUICKLY. You will know if it is over heating! Also there may well be a burning smell.
The headlight relay switch should be under the hood in the fuse box. Not sure which one turn the lid over it should have a diagram.
It's on the passenger's side in front of the rear wheel. Use two wrences on each fitting. Either depressurize the system by pressing on the schrader valve under the hood (with a rag over it) or wear safety goggles. No smoking please.
get under the car and reach between bumper and radiator and slide the hook over and u can open the hood
