I also did, primarily because I felt the races would be much more annoying with the crap visibility made worse by helicopter dust and searchlights and the PR Stunts definitely would be as Drift Zones, so I wanted to get it all out of the way first.
And I was right. Everything was much nicer after that.
Edit: Okay, what the smeg? I always try out - when I have time - the EventLabs for each season before they go live and... I just don't get it. Why are they consistently picking these creations?
One of them is okay, I guess, while the other is a boring as hell loop with grabby walls (because they're overlaid badly and in the wrong direction, again), makes some bizarre claims about cops in the description (there are no cops), and the creator has used the custom ruleset to put what looks like ASCII kitten smileys and an advert for their own YouTube channel in the race data boxes in the corner. And both are absolute crap as a solo lap; Playlist EventLabs are always one-car events, for no reason I can determine, and even decent ones suck without any AI.
The only thing they appear to have in common is that the creators have spent approximately 1800% of the props budget somehow on making a city environment (LA and I think Hong Kong) for them which results in a framerate on the Xbox Series X of about three* again. Christ alone only knows what it'll be like on Xbox One. Did anyone actually try them to see if they're playable?
A bad track with no opponents isn't a good event just because it has a completely different setting achieved through use of props. For the love of bees, pick an interesting circuit with some creative use of the way you can change rules and physics and PUT SOME BASTARD AI IN THE RACES. Especially if you're going to burn through two a week; the bottom of the barrel will be scraped through to Mauritius before long.
*Okay, 60 most of the time with some very obvious drops to 25ish.
