Formula 1 needs to move away from tracks that are like 'supermarket car parks' and race more at old-school venues like Monaco, claims Mercedes motorsport boss Toto Wolff.
Wolff says his perspective on what F1 needs to be has changed after spending last week competing in the famous Italian Mille Miglia road race.
He is convinced F1 needs to do more to make sure aspects of it that are attractive for fans are embraced, like races taking place on challenging circuits.
"The DNA of F1 was about the best technology ,with the best drivers sitting on a bullet and trying to drive that bullet," explained Wolff.
"Somehow [on the Mille Miglia] this became clear to me why I love this sport.
"It is about doing something that nobody else dared to do, and with the passion for cars.
"Motor racing is a life, and there is so much passion and so much emotion, throughout all the generation for cars and drivers.
"To drive these cars today you need courage, more on some tracks than others, and we don't want to race on tracks that are like supermarket car parks.
"When you missed a corner in the old days you were dead or hurt. Today, you miss a corner, you run wide and rejoin.
"But not in Monte Carlo, maybe not in Spa, maybe not in Monza, and maybe not in Suzuka.
"We need to go back to tracks where you realise who the best are.
"This [Monaco] is one of those tracks. This is where we need to go back."
Wolff thinks one solution would be to add more street venues to the calendar.
"It is not only about watching the Mille Miglia and seeing you can go quite fast in cities," he said.
"The success of [street-based electric single-seater series] Formula E is being in town. The cars are not spectacular but they look fast in a city context, and you can see the attraction of Monte Carlo.
"So I think we should be moving away from the airport-like structures. It is not spectacular.
"I can sit in an F1 car [at tracks with run-off]. Give me two weeks of training, I will spin the car 100 times, I will look at the data and maybe I will go quite fast because maybe there is no risk."
