On this episode of the Autosport Podcast, Kevin Turner set out to ask BTCC Commentator and now author David Addison a very important question: "Who are the 'immortals' of British Motorsport? The most impactful drivers and figures that have shaped, moulded and moved the needle for the sport domestically? In a new book, "The Immortals of British Motor Racing", David breaks down who for him, are his 12 drivers in British racing with the greatest legacies.While some names fill themselves in like Sirs Hamilton, Stewart and Clark, some others may surprise you like Gerry Marshall, or driver turned broadcaster Martin Brundle.There's also some discussion about the honorable mentions that didn't quite make the book, like Britain's first F1 World Champion Mike Hawthorn, or Grand Prix winner John Watson. Who do you think should have made Addison's twelve? Let us know in the comments!Learn more about your ad choices. Visit podcastchoices.com/adchoices
