It's all relative! Think of it this way: from the point of view of someone inside the car, the drone is staying right in one spot, so compared to them, it's stationary. But, if someone were standing outside the car watching it go by, they'd see the drone moving along with the car at 50 kilometers per hour. The drone is propelling itself, but mainly just to stay hovering in the air inside the car. Now, whether it was moving with the car or propelled by it depends on how you measure it. Inside the car, its speed is zero. But outside, it's moving 50 kilometers per hour with the car, just like you are, even though you're sitting still. The car's engine is doing all the work to push through the air resistance, so the drone doesn't need to do that. When the windows are up, the drone is basically flying in that sheltered pocket of air inside, but open them, and you introduce that wind resistance, which makes it a lot more work for the drone to maintain. 1. Windows Closed (No Wind Resistance)
When the windows are up, the air inside the car is moving at the same speed as the car. Because the air is "trapped," the drone doesn't feel any wind pushing it backward.
Thrust: The drone only needs to provide upward thrust to counteract gravity and hover.
Movement: It doesn't need to provide forward thrust because it is already moving at 50 km/h relative to the ground (inherited from the car's motion), and there is no air resistance trying to slow it down.
2. Windows Open (Wind Resistance)
The moment you open the windows, "new" air from outsideāwhich is stationary relative to the roadārushes into the car. From the drone's perspective, this feels like a 50 km/h wind hitting it.
Thrust: The drone must now provide both upward thrust (to stay in the air) and forward thrust (to fight the wind).
The Angle: To create this forward thrust, the drone will actually tilt forward. By angling itself, some of the air pushed by the rotors goes backward, which pushes the drone forward. its position.
