This is what we're trying to do with Mathesar (https://github.com/centerofci/mathesar). We probably don't meet your needs yet because we don't support real-time concurrent editing, but we're actively working on the project and it is early days.
It was pretty scary. I would slow down when people or animals were in the path of the car, but my driving instructor didn't like that. He insisted that I should go full speed ahead and trust that anyone in my path would get out of the way.
My driving lessons (in India) did include a few hours in an arcade-style simulator before we went on the road.
I've tried driving lessons in the US and they don't seem to include simulators. People actually follow traffic rules here and there are lots of quiet (low traffic) streets, so it's not as intimidating to be on the road.
