I feel like the slippery circle on the automation track isn't slippery enough. It looks and feels like water, but I just think it would be cool if it's the same type of soap they use on actual slippery courses IRL. The ETK driver experience center has a nice patch that is as slippery as I would expect. When removing the electric locking diffs and putting a turbo on it gets a lot better and you can put some power down, but would be really cool to have a circle with actual soap.
Definitely noticed this as well, does not seem too realistic, a bit too grippy to be considered drifting on water. I mean look at this video: Even this is more slippery than the game.
