You can usually limit the bike to go less than 20mph in those cases.

It would be nice to have the GPS automatically set the pedal assist max speed when riding on shared paths with pedestrians and people.

I have also seen road bikers on those same shared paths pedal faster than 20mph.

No consumer GPS is precise enough to reliably distinguish between a bike path and an adjacent regular road, especially if there are any overhead obstructions nearby. Many bike paths don't have a 20mph speed limit anyway.
