Played about 5 hours or so, already at 35% completion.
I chose the BRZ as the starting car, switched to the S2000 as soon as I could, bought the available upgrades and since then I'm using that, visiting the shop every 5 levels, getting all the stuff maxed. I'm close to saving up for some 112k Porsche, that's probably a good enough car for the endgame.
The rubber banding is definitely reduced, apart from the first few races, I managed to win all of them, even with crashing and missing turns one or two times per race.
As far as traffic goes highways are pretty much empty yet in this 5 hours I managed to crash more than in ~100 hours of FH2 as you only meet these fuckers in turns while drifting.
Game modes are mostly drifting which is fine by me as I got the hang of it pretty fast and it looks great with the new camera (which I love btw). Drift train is some unbelieveable bullshit though. Your so called teammates drive around 100-150kph constantly which is just a bit too low for my optimal curves. If you stay behind or ahead, you miss the points, otherwise they just crash into you.
Collision handling is inconsistent too as sometimes crashing into walls still awards you the drift score yet drift tapping (which was a nice addition in FH2) or touching cars makes you lose the points.
Customization is kinda useless currently as painting and decaling doesn't work. My S2k has 1 ugly af custom taillight available with 4 huge ass spoilers and 4 types of hoods. Even the first Most Wanted had more options. I guess options gonna be worse on a Porsche or a Ferrari.
The drift-grip sliders work well and make a difference but considering how easy it is to drift without losing any speed I don't se any reason to go with grip.
I guess I'll go as far in the story as I can, then finish it up from the Vault.
