It was something that PD and the FIA were jointly working on.
It really isn't.
There's four things you need to do to get a racing licence. The first is medical certification that you probably won't drop dead while driving. The second is to pay some money (~£200) and go to a certified instructor at a driving school. Third is you watch a 30-minute video (it may not even be that long, actually; it just seemed long) and answer a bunch of multiple-choice questions and a couple of written questions to check you understood the video. Finally you go out on track for a couple of laps at walking pace to show you can follow a racing line around a track. Once everything is stamped, you give it and £50 to your local motorsport governing body.
That's it. That's literally all of it.
The FIA and PD both still think that.
In principle they're right. If you drive in GT Sport and follow a racing line, you've done the practical bit. If you watch the Racing Etiquette videos you've done half the theory bit. The yellow, green, blue, and chequered flags cover most of the other half.
What's missing is the other flags (black, black/white, national) and marshalling (seriously, half the multiple choice questions have the answer of "follow the marshalls' instructions"). If the game had that, it would be a perfectly adequate substitute for the National B Licence test... but your local motorsport body would probably still want the £50 you pay them for the application...
