Wind turbines do not charge car battery on hippy van

[Duhuh54321]

Describe the bug
Wind turbine does not charge battery when I install it on a hippy van.

To Reproduce
Steps to reproduce the behavior:

1. Start at evacuation shelter.
2. Spawn hippy van, 2 car batteries, 2 wind turbines, 1 toolbox
3. Set mechanic to 10 and install the parts to the van.
4. Remove the existing battery of the van, which has 100% charges
5. Wait. And notice that the two 0% battery never get charged.

Test at place not near forest

6. Remove the two 0% batteries. Install 100% battery.
7. Drive van to place not near forest.
8. Remove the ~100% battery. install the 0% batteries.
9. Wait. And notice that the two 0% battery never get charged.

Test removing roof

10. Remove the roof tiles of the car that are below the wind turbines.
11. Wait. And notice that the two 0% battery never get charged.

Expected behavior
Expect car batteries get charged. I think I can install the wind turbine above the roof. Other parts of the car should not make the wind turbines stop working.

Removing the roofs and boards around the turbines allowed them to start charging.
This is down to the if( g->is_sheltered( global_part_pos3( part ) ) ) { continue; }

Confirmed, yet will need to look into it some more, to disable surrounding vehicle parts as wind blockers. ( the assumption is that its taller than other parts )
