Here's a very common snow removal vehicle: http://image.dieselpowermag.com/f/tech/11090507+w799+h499+cr... This type of vehicle is used all winter on the narrow paths, sidewalks, and streets at the University of Michigan. Snow levels at U-M are very similar to those in Detroit. I imagine that these vehicles are probably a lot cheaper than the snow plows used for wide streets too.
While googling for that image, I also found this, which I thought was pretty cool: https://www.arcsfoundation.org/minnesota/news/its-time-annua...
Here is the information that Go Read stores per user: https://github.com/mjibson/goread/blob/master/goapp/types.go...
I'm not sure that's strictly true. For one, if the government is paying for those who cannot afford it (through medicare/medicaid, etc.) then there is money to be made, and thus some incentive. Even if its a relatively small amount, some model could be devised to capture the market as a sort of long tail. Much like Amazon has some incentive to sell even the cheapest, niche items.
