What a long winter it must have been for Sebastian Vettel.
How tempting to dwell on the turning points that lost him the 2018 world championship.

Championship-winning opportunities like 2018 don't come along very often, and missing out on them can add some serious baggage to a driver's career. There is no way of knowing how the season would have panned out had he not made those errors -- perhaps Hamilton still would have emerged victorious with a superior car in the last few races -- but arguably that 'what if?
