Hi! Would it be possible to have the option of automatically picking up the vehicle when we disembark? I'm always forgetting my cars :)

Yes, me too!
Unfortunately, when I made the mod, I concluded that:

1. It's not possible while preserving the contents of any equipment grid on the vehicle.

2. If I forcefully "mine" the vehicle like you mine a tree/etc, it preserves the grid, but I can't translate the cursor position to an ingame tile x/y coordinate. So I can't either move the cursor to the vehicle or opposite.

1 might be possible, just that I was unable to figure it out at the time.

Thanks :)

Should be optional. What if your car is packed with stuff? It holds more than you can.

It is optional, there is a runtime per-user setting for it.
