Right. I use doordash all the time, and pay $5 - $10 for delivery. It gives me occasional status updates on my delivery, but no real time tracking. I'd love to see this in doordash, and if it costs them $0.04 from the $5 fee it seems like a no brainer. Same for so many other similar services.
IIRC, doordash used to provide a live map a couple years back. I'm guessing they have all the data and could share it again if they desired. Presumably they have some product reason for not offering it.
They still do around here (Boston, MA).
The question is why should I even pay you $1 cent for a service for which existing underlying APIs are already extremely good( android or iOS location API and Google Maps API )
