Once you have completed your card, you can access the individual link to it at the top right via “Share”. Simply send this to everyone who should come to the meeting point – this also works well on mobile phones, although of course it cannot and should not replace proper navigation.
You can also work together on such maps by activating the “Allow editing” function in the same sharing dialog. In this way, all participants with the link can use the above functions themselves – practical if you are planning a road trip together.
Since you have the entire world map at your disposal, there are literally no limits to what you can do.
