another 'one' for Sebastion

Another one

Intelagos, Round 19: Sebastion takes another record in scooping the pole position tally to fifteen for a season from the great Nigel Mansell in 1992 who previously held the record for a number of years at forteen. Hang on, just how many races were there in the season Nige took the record??  Now that would only be sixteen races.. mmm??
