The Detroit bus company has a good as needed business model. They don’t have regular routes but a phone app tells you were the closest bus will be so you can meet it or even call for it to come to you.
And best of all, they advertize that drinking alcohol is allowed on their buses which clinches the deal and proves that they don’t get taxpayer dollars.
