Love London transport? Join us in the Londonist Roundel Ramblings Facebook group for a spot of geeky fun.

Did you know, you can slap a tube map on just about anything? Case in point: the Ferrari above.
See, we thought cars would be one hurdle too far for the tube map. Isn't the automobile competition for the Underground? Well, it matters not, because Ferrari has gone and done it anyway.
Now the more astute among you will immediately notice this isn't the actual tube map, but rather, it's something inspired by Harry Beck's classic. The stops are the circuits that will host Ferrari's upcoming UK Challenge Series (yes, we know, none of them are in London).

The car looks to be one of a kind — a shame, as it's definitely something we could have seen as the next tube inspired must-have on the streets of London. Or at least the streets of Knightsbridge. Alas.
Thanks to Jack Haywood for the tip off on Roundel Ramblings.
