Will food delivery from grocery stores catch-on in metro Detroit ?
Warren + SterlingHeights population = 250,000 thousand people
Meijer/Kroger/Walmart does home delivery , Amazon/WholeFoods wants to, etc., etc

Detroit is an impoverished area where median income is at $24,000.
Almost half of Detroit’s working-age residents aren’t even looking for a job
— at 53.4 percent, it's the lowest workforce participation rate in the nation
and a symptom of poverty and poor educational attainment.
Then you have the "other" part of population becoming retired in next few years.
