Detroit's mayor Mike Duggan mentioning that he prefers the QLine with dedicated lanes. If and when the city gets funding, it would extend the line past New Center up Woodward and he also envisions a line going down Jefferson east of downtown.
So at the very least, the Mayor is on board with expanding the system. The biggest uncertainty at this point is whether the city's finances are ready to cover construction and maintenance costs of even just the current 3.3 miles let alone an expansion. Still quite a ways away from the city taking ownership of local transit.
