But the 58-year-old Italian went straight back into the paddock in Bahrain as an analyst for Sky Germany, and at last weekend's Australian Grand Prix he conducted the top three interviews.
Now, Steiner will also act as an ambassador for the upcoming Miami Grand Prix in May, helping to promote one of the championship's most recent additions to the calendar.
“I’m excited to serve as an Ambassador for the Miami Grand Prix, which has become one of my favourite races of the year,” said Steiner.
“I’ve seen first-hand the incredible growth Formula 1 has had in the United States and it has so much potential to continue growing, especially with races like Miami as part of the circuit.
"The event, which reflects the bold vision of the organisers, pairs American spectacle and F1 racing with a vibrant atmosphere at the track and throughout the city itself."
