SAKHIR, Bahrain (Reuters) - Triple world champion Jackie Stewart said he had likely driven his last lap in a Formula One car after steering his title-winning 1973 Tyrrell around the Bahrain Grand Prix circuit at the age of 85.
The Scot - world champion in 1969, 1971 and 1973 - made light of the afternoon heat as he drove around at a relatively leisurely pace behind the safety car ahead of Sunday's race start.
