Interesting article - thanks for sharing it. I've had some limited involvement as a GIS expert brought into assist the IT department in dealing with a geofencing solution they agreed to use with various ride sharing companies that use the facility I am employed at.

I can't say much but there were multiple issues that could have been easily avoided with a basic understanding of GIS - I have no doubt that some of it was due to the IT department at my employer but am also incredibly surprised that any GIS staff at the ride share companies would have agreed to what was implemented.
