They are two main points which I love most about sharing on google maps to add helpful tips for travelers and help avoid close and non-existing places.
I love to travel. Therefore, I like to share my experiences on google maps such hidden tips to get best experiences from visited places. I visited famous Maj lookout in Czech Republic which is crowded most of time. I shared in my review tips how to avoid crowd and get better view.
I do edits if need it as example I was running out of gas and looking for gas station in Northern Australia. I arrived at location pointed by google maps. There was no gas station and never was. I immediately edit this place in order to avoid same disappointing experiences for other travelers with empty tank.
