What would happen if a car is driving down a highway at 80Mph and one of the doors is fully opened. Will it make a big change and make it slow down or start turning?

What I'd like to know is how are you going to GET it open and how will you KEEP it open? 80Mph wind against a car door is going to be a LOT of force. I doubt one person could do it, particularly given the odd angle at which you'd have to exert the force. If you tried to walk in an 80mph wind, holding a car door directly against the wind, I'm sure you could not stay upright.Tech2025 said:What would happen if a car is driving down a highway at 80Mph and one of the doors is fully opened.

There is a lot of special effects expertise that could be brought in here.When they want to slip a car into a roll, they fit a ram underneath which lifts the side of the car up. The same sort of force would be needed and I'm sure it would be simple bread and butter stuff. But you are right; an arm and shoulder wouldn't do the job.phinds said:What I'd like to know is how are you going to GET it open and how will you KEEP it open?
I bow to your superior knowledge there.Outhouse said:A door open will not cause lift, and doors have different shapes that will have different effects.
Well, any yaw asymmetry anyway. Pitch asymmetry (e.g. sticking your hand up from dead center in the sun roof) would have no relevant effect.CWatters said:_Any_ assymetry to the drag force on a car would in theory require some steering input to correct. It's a question of degree.
Opening a car door at high speed can lead to serious injuries or accidents. The sudden rush of air can cause the door to swing open with great force, potentially hitting other vehicles or pedestrians. It can also cause the person opening the door to lose their balance and fall out of the car, resulting in injuries.
Yes, opening a car door at high speed can potentially damage the car. The force of the wind can cause the door to bend or even break off its hinges. This can result in expensive repairs and may render the car unusable until it is fixed.
In most places, it is not explicitly illegal to open a car door at high speed. However, it can be considered reckless or careless driving, which is a traffic violation. It can also be considered a contributing factor to accidents and may result in legal consequences.
The best way to open a car door at high speed is to first slow down the car and come to a complete stop. This will reduce the force of the wind and make it easier to control the door. Then, use one hand to hold onto the door handle and the other hand to support yourself. Open the door slowly and carefully, ensuring that there are no other vehicles or pedestrians nearby.
Yes, opening a car door at high speed can cause a sudden change in air pressure inside the car. This can result in discomfort or even ear pain for the passengers, especially if they have existing ear or sinus issues. It is recommended to open the windows slightly to equalize the air pressure before opening the door at high speed.
