Welcome to the Jalopnik Weekend Motorsports Roundup, where we let you know what’s going on in the world of racing, where you can see it, and where you can talk about it all in one convenient place. Where else would you want to spend your weekend?

Detroit is the popular place to be this weekend, with the Verizon IndyCar Series and IMSA WeatherTech SportsCar Championship heading the race weekend at Belle Isle Park. But it’s not popular with everyone—there are groups protesting car races at the park, with the Detroit Free Press reporting that protesters say the grand prix “upsets … the whole ecosystem” at the park. Regardless, the cars will be there this weekend.
