Hard to gauge. I can’t say I struggled (Waznewz tuned '05 Vauxhall Monaro VXR) but it took a little to work to the front and there were some lead changes in spots but easy enough to regain. I’d say it was a good race, par for Highly Skilled.
EDIT : PS… oh yeah, definitely more challenging than the Trial… not that I’m complaining 
I can’t actually get the first stage of Campout to trigger. I have tried. Restart. Delete car and re purchase. Tried switching between horizon and solo.
Did it twice, had no issues, quite the opposite in fact. My 2013 Shelby GT500 tore them to pieces. Finished several turns ahead by the end. Friends were also struggling to keep up with that car though, so maybe it’s meta? Though my friend was experimenting with a grip build that race that I think ended up being bad. He still beat the drivatars though.
Second time was in the RTR Mustang, had more trouble there, but not much. Certainly not any trouble worth mentioning. Friends were better able to keep up with that car too.
Trial I found a harder challenge but still 2 1sts in 2 races to win the event. My 2011 Impreza was ok. It really struggled to catch up to first on the second race, mostly doing so by taking better lines. Definitely a harder trial than championship from my perspective though.
Wow, that second event lab really sucks! It’s almost undriveable and it lags like crazy on my One X. I hope they pick better event labs next week!
for me I’ve tuned car to A800
For me the Shelby Mustang GT500 2013 was the car for the championship street race I converted it to AWD and tore through the opposition Drivatar formation train had to bully a few of them out the way but that is justified.
Easy first time trial success in the 22b with GreetedDusts tune. 1st in race 1, then 2nd to an AI after I got a biiig bump at the start. I smelt it and managed to angle myself so I didn’t lose too much speed. Slow in fast out gosh darn it. 
Edit: Festival of Forzakart - loved it. I used a 96 Impala and it made me feel smug to connect the drifts and enjoy another crazy replay. Only thing I found annoying was the beachballs.
Finally I got the team I deserve in the trial and easy win in 2 races.
Try all cars and run all Spring and just no Treasure hunt message pop up.
Still no help tuning the tire pressure
Nope same for me.
“This content isn’t available as it hasn’t been downloaded” or some such nonsense. It advises that I need to be in Horizon Life (I already am) to access it. I’ve tried going to Solo and back again, but nothing? How do you force download something that’s not even DLC? 
Restart the game.

I’m done wit the playlist might do the rest of the dailies but I don’t need to, as I have already unlocked all the cars.
I hear that, but this Treasure Hunt bug is annoying because there’s two Accolades behind it that may never unlock at this rate. Well it feels like it may be never, because if my patience breaks I’ll just bin this game as it seems to be begging for that.
And the last one I had bugged, that the devs so generously retroactively completed did not advance said Accolades fwiw. So, thanks for the half measure.
Being a fan of Modern Muscle I liked the championship. I started with a 13 Mustang which was great but I was tired of the Forza wing. So I started over with the 13 GT500 with stock aero, then a Hellcat with the LW spoiler and finally a CTS-V with stock aero. They’re a bit closer to a real world build that I would like. All handled the championship easily and shared as “Road V8 No Wing”.
I ran the Trial a few times this season. It’s been pretty nice. Yes I’ve seen players not able to handle their Impreza or Lancer and blast straight into a wall or just slide around in general. Sometimes though I find myself getting tunnel vision watching them and end up following them into the wall. I didn’t see any door banging or fighting over the win. It’s been entertaining. I used a 22B first and then have run it in a 04 Impreza and a 08 Lancer. They all did well
I’ve done all the horizon tour accolades apart from win a tour in an S2 car.
Because there’s no S2 class, in tour…
JFC…
And apparently I now have to buy a 10million crapy subaru (22b) to get another accolade from the auction house.
It gets better…
There’s a 20million buy, and buy 400 cars from the Autoshow (my god the grinds)… I’m almost there on the Autoshow buyout lol. Three to go. Kind of waiting for those Daily “challenges” of “Buy an Autoshow Car” to finish it off.
not here too, @Not_Here_Too - exactly as you write, got the message but nothing spawned and the playlist tile didn’t change
I got the treasure chest but it didn’t show what is inside after I hit it.
So it’s empty is time?
