I’m amused that the first step given by the Google Maps public transit directions in Detroit is: “Drive a car”
I guess cars are considered public transit in motor city.
Update: To be fair to Detroit, there actually is public transport to and from the airport. I took a city bus from my hotel to the airport to catch my departing flight, and it was clean, inexpensive ($2), and dropped off right outside the terminal. I think perhaps they simply weren’t running that late in the evening when I flew in, leaving driving or taxi/Lyft/Uber as the only other reasonable alternative to get downtown.
