Correct - but the starting point here was already 'take this path', not 'go to that location on the grass'.

Come to think about it - even 'just park somewhere' is remarkably complicated. I don't quite understand why self-driving cars should need external high quality maps and can't make do with onboard cameras as human drivers do.

But then the parking requires either a high-quality database of valid and off-limits parking locations, or the ability of the car to read the signs on parking lots and generally be able to distinguish private from public parking.
