So, there's a special version of London at 2:26 that nobody knows if it exists already or will be added ever. All we know is that the McLaren have turned their lights on.
Than, just some seconds later, we see some X2010 in a row turning on their head lights one after another.
What do we conclude? PD maybe used the L1 button! 💡
Maybe they didn't, and maybe I really recognized the track where the X2010's are right and it's the Red Bull Hangar-7 again... damn, PD showed us this track so many times, why can't we get it into the game?? Even as drag strip only it would be nice because of the evening atmosphere.
Oh, and the test track with the X2010 speeding on in the last scene... kinda looks like the good old test track. Maybe PD is going to give this track to us as later... well, of course in a DLC that costs money then.
But after all, these things aren't surely said, just guessing from what what can be seen in the video. And there's even a nice engine sound coming from an SLS and we all know that it sounds much worse in the actual game. To me this all seems like PD just edited the scenes quite a lot.
