the mod is perfect with my tank mod (heavytank)
but when driving the most powerful tank at full speed, still hit some trees.
Dont know how much this mod impact on UPS to change the speed of the script, but will be better if the area was in front of the vehicle instead in the center.

I think the issue here is that the tank is probably faster moving than the mod can clear the trees in it's path. One of the solutions would be to increase the range at which it will start breaking the trees. I can create a special rule for your tank but I would need to know the tank name ingame in a way that I could detect it with the following command: "vehicle.name == "car"" the car would be replaced with your tank name. Also if you are on discord then find me in the Factorio discord server under De7ilx#7777 name or just add me. I can give you the modified file before uploading so you can verify if it works as intended or not.
