Motor Sport Podcast
Annoyingly, you now have to register to access the Motor Sport podcast. I have done so very recently, being careful to not tick the boxes that would invite marketing e-mails, and so far only received an introductory e-mail. I will update this if they e-mail again. Generally, I recommend the podcasts, which have included some fascinating interviews with such as Mario Andretti, Christian Horner, Patrick Head, Jochen Mass, et cetera, but truth be told, one of the recent ones I found a bit boring.
(My advice is to keep a spare e-mail address for when web-sites want them but you do not want to risk cluttering your regular e-mail account with unwanted stuff.)
