So it looks like we’re heading for a title showdown, either this weekend in Saudi Arabia, or next in Abu Dhabi. And what a season it has been. But whoever emerges victor in the final two rounds of the Max and Lewis show it is unlikely the title will be determined on the very last lap of the very last race and absolutely impossible for three different drivers to be champion elect on that lap. Because even if there were three contenders, that would be too implausible? Surely? Surely not. At various points during the last lap of the 1964 Mexican Grand Prix, there were indeed three drivers who had every right to think the title was theirs.
