After colliding with Mick Schumacher in the first of two US-based races this year, the four-time world champion retired from the inaugural Miami Grand Prix.

The race was established to capitalise on F1's growing popularity in the United States, but it skipped more historically significant tracks in the country, such as the Indianapolis Motor Speedway, which held the US Grand Prix in the 2000s.

Vettel made his Formula One debut for BMW Sauber at IMS, but with the addition of Miami and Las Vegas to the calendar, he was asked if a circuit like the site of the Indy 500 could fit with the new scheduling trend.

Vettel commented during Friday's press conference ahead of the Miami Grand Prix: "I'm not sure if I'm the right person to judge because obviously, there's always personal flavour."

He continues, "I think the US has fantastic race circuits with incredible history. Obviously, creating a circuit here is a very different interest. So racing in the cities is exciting because people are already there. You don't need to excite the people, because in the first place, they are already close. But certainly from a racing or driving point of view, I think racing… I think Indianapolis is a bit of a half racetrack. If you're not racing on the oval, you're not doing the real thing."

"Going to Road America.... for certainly the money that was spent to build this could have easily, you know, brought the standard up in great places like Road America," Vettel said, describing a circuit he would want to see on the F1 calendar.

Vettel adds, "From a driving point of view, I think they would be a lot more thrilling. From a fan point of view. I think that's difficult for me to judge because the last time I sat on the grandstand to watch the race was in 2001. So, a long time ago, and yeah, every fan is different. So I guess it's more for the fans in a way to decide. But certainly, from a racing and driving thrill, I'd love to go to proper tracks."

Current IndyCar driver Graham Rahal and his legendary father Bobby have offered the German an opportunity to test one of their cars at the legendary venue. When asked about it after the race, Vettel said: "I need to have a look! But it’s a great track so let’s see."
