Automobilista 2 to Implement Wet Racing Line Physics?

When it starts to rain, a race can change in an instant. Sim racers are often used to mostly dry conditions, but have to face the tricky task of navigating a circuit with considerably less grip once the heavens open up. The simulation of a correct wet line has been lacking in simulations thus far, however - but Automobilista 2 might change this in the future.

For most sims, rainy conditions mostly mean reduced grip and puddles in key places, which some titles generate in fixed positions while others accurately calculate them depending on the state of the track. What is not really taken into account is the behavior of cars on what would be the racing line in the dry - real-world racers would tend to avoid that when a session transitions from dry to wet.

The reason is simple: Over time, cars lay down tire rubber on the racing line in the dry, increasing its grip. Once it starts raining, this rubbered-in line starts to become more slippery, so drivers stick to a wet line until all the rubber is washed away and the previous line becomes less treacherous.

Simioni Teases New Feature​

This is something sim racers might have to take into account in Automobilista 2 soon: A discussion on the Reiza Studios forums about this topic prompted Lead Developer Renato Simioni to answer a question regarding the lack of grip on a wet racing line as follows: "Reduced grip on racing line rubber when wt is not currently simulated in AMS2. Emphasis on "currently":whistling:".

AMS2 uses the Madness Engine and its Live Track system, meaning the state of a circuit changes accurately through calculations rather than baked-in effects. An update to the tire physics is in the works for v1.5 and due to be released in late June - so some patience is needed to find out if this feature is going to be part of this update already.

I think you are jumping to conclusions too quickly based on nothing much.
After, if you are right it would be very good if it is well implemented by Reiza.
Well, an opportunity for me to say a big thank you again, thank you Reiza for your hard work to offer us this splendid simulation that some love to demolish with comments that I will not qualify.
 
For proper wet weather racing simulation they need to make your monitor fog up and have you race in wet socks. Phooey to wet racing.

I would add that PC2 was better in terms of the AI would adapt to rain more closely to the player. When it rains in AMS2, I'm on ice where as the AI streak off in the distance. In PC2, I still have a chance.
 
The question was different: how much does the rubbered dry line become less advantageous at the start of raining until rubbering is zeroed when the original dry line becomes the best even in wet conditions.
From what I know only ACC claimed to do so insofar, but I have seen the claim disproven by Moritz Lohner in a recent stream.
Is RF2 simulating this?

Tbh. I don't know if that part is simulated by rF2. I know it's dynamic. However, when it comes to rubber being slippery (as it should) or not, I honestly haven't read anything about, or tested myself.

Maybe I'll find out in the RD Club race today!

Contrary to what others have said here, AFAIK, no sim has simulated this so far.

Would love this feature. However, it saddens me 99% of the people can't drive in wets or they just quit when they see its gonna pour
 
Stupid high grip for slicks on a wet track, and uses different inputs when comparing on and off the ideal line driving. Oh I'm so surprised that he lost it on the inside flooring the throttle at the apex of T1, but didn't when going half a meter to the outside and refraining from accelerating fully until its almost straight, and still spun then and there. Plus, as a watcher you cannot see on the video where the puddles lie around the track with the quality displayed there.

This video proofs nothing, stronger evidence is needed.
