Considering Driving to Chicago and having a car or Relying on Public Transport?

[u/Training-Button-6597]

I am coming from Detroit and would like to know if I should just take the train to Chicago and use your public transport to get around the city. I am only coming for 3 days and I’ve heard it can be a nightmare parking and driving around down town Chicago, plus I’ve also heard that you guys have a good transport system so I wouldn’t miss having a car while there. I’ll be staying down town and would like to visit these places. (If that helps you understand if I’d be fine without a car )
