If You Could Design the Perfect City, How Would You Make It More Car-Friendly?

Aside from our daily travails with terrible traffic you ever think about your Cities layout?

It’s not just the birthplace of the auto industry, but everything from the layout of Woodward Avenue and the loop to the Detroit Grand Prix running right through the streets shows how deeply cars are woven into the city’s DNA.
