I'm not saying it won't take aeons to bleed with a long hose and gravity, but its free and you can do it by yourself.
Its interesting looking at this software and the control over the whole brake system. I feel like If the resovoir were bigger, the car could almost be programmed to bleed out the bubbles itself
By the way if your fluid is green and you open the cap and see patches of what looks like oil, water or water lillies, you are already WAY overdue for your brake fluid. Its typically done every 2 to 4 years on a non-track car, though in my city I've seen people go over ten years. Its magic that their brakes didn't outright fail.
