Some info from me.
Progression: In 4,5hours I’ve managed to earn around 1mil and level 16. Have not bought anything besides few upgrades for starting car. It looks like price in connected with PI of the car e.g. 404PI Merc SLK was 250k, Audi TT was 500k, BMW M4 was 800k and 600PI Porsche Taycan was 1,5mil. Can’t remember PI for Audi and BMW, but it was pretty linear.
Don’t know how I feel about cars behind “double barrier” - money and your level.
It looks like there will be some daily events/missions in the future, which looks interesting.
Races/difficulty: IDK, sometimes I was finishing with 20sec gap to 2nd, sometimes I had to block AI, and sometimes I had to pray to finish on podium. I don’t understand why AI doesn’t even up to players PI. No idea how is that supposed to work. Especially with open bracket e.g. PI 500-600 and I’m in 550PI and AI in 586PI car.
That always online/multiplayer mode is annoying too, cause even if you are only real person, you can’t pause. There is also no “restart” in races, so you either have to leave race and start over or finish race and restart from finishing screen. There are some solo races, but most of them are “multiplayer”.
Physics: IMO full arcade.
I’m playing on keyboard. Without TCS/ABS ON it was playable, but understandably with ABS OFF it was locking up and with TCS OFF I had issues with uncontrollable snap oversteer at higher speeds. I’ve spent 95% of the time in starting car (Mustang). AWD cars had better launch, but every car felt pretty similar.
Maybe on wheel/controller it is better experience.
In chase cam car moves weirdly, especially when they are in the air. With bumper/hood cam it felt better.
Graphics: That was first time when I heard fans in my new PC 
And that was on “low”.
Funnily enough, after changing settings to “high” and 2 restarts it was working better. Was not going below 45FPS.
IMO visually it is not even close to FH. Maybe there is a reason we don’t have big city in FH.
Map: (roads) I liked the hills and docks. City was meh, maybe roads are too wide?. Dirt was not enjoyable probably because of physics.
It was interesting to have “alternative” routes - many races have roads with medians and you can decide which side to use.
Aboslutely hate trees, lampposts and curbs. Fact that most city tracks uses 90 degrees corners where you can just cut through sidewalk is 
. Not as dumb as some “extensions” in FH street scene races, but still.
(house/clubs/showrooms) 50/50 on that. On one side it is nice to “stretch your legs”. Showrooms have so much wasted space. Everything is so fancy, but maybe that is just me. I’m keeping low profile 
UI: Not a fan. Still can’t understand why ABS/TCS is under car menu and not in settings.
But worst part is starting/finishing race. Start - cause you are forced to “invite” other people and can’t decide when to start and all you can do is wait. Finish - cause there is so many “finishing screens” and it takes sooo long (I may be exaggerating a bit, but there are many screens).
Map icons are terrible visually - it is hard for me to tell which are new, and which I’ve already completed. Snapping to icons is too strong.
Modifying cars/parts: Not a fan of using common/epic/legendary markings, but at the same time using name street/sport/race without colors is not that much different.
I hate the fact that parts are locked. same as cars, behind double barrier.
Still can’t understand why my turbo is not making any pressure.
Also still have no idea what “driving mode” is doing. Can’t feel differnce between them.
Minor annoyance:
Can’t change cars anywhere, only near garages/showrooms. Maybe that unlocks later.
That when I use “back view camera” it doesn’t rotate the map.
Summary:
Not a fan, can’t recommend.
Feels like mobile game with high requirements.
It was fun to do night runs with bumper cam. And that is where it will probably shine. Free roam driving.
PS. sorry for wall of text and probably still have forgot something 
I was going to pre order but based on the demo i will, initially, be saving my money, unless they make vast improvements over the next 3 months.
. Sometimes FPS drop below 30 or even 20, but it looks pretty nice now.
It gives nice rally stage vibes.
