Custom browser script to show real-time weather grip coefficients on all tracks

Hiro_X54 (KR) Xp: 27979
Hey everyone. I got tired of guessing how much grip I actually have left when transitioning from sunny to foggy weather in the middle of career mode, so I put together a basic user script to help with that. It is a simple Tampermonkey mod that injects a small telemetry overlay into the game UI.

Currently, it pulls your active car upgrades (engine, tires, and nitro levels) and calculates a real-time traction percentage based on the current track and weather conditions. For example, if you are running level 3 tires on Overpass during a rain race, it will show your exact grip loss compared to sunny conditions. I also added a small visual indicator for nitro efficiency, which is super useful on Skyline when you need to know the exact moment to burn your boost without spinning out.

I have tested it on Chrome and Firefox, and it runs perfectly without hurting the game's performance. It is strictly client-side visual telemetry, so it does not violate any fair play rules or trigger the anti-cheat. You can grab the script from my Github repository (link in my profile, do not want to trigger spam filters here). Let me know if you run into any bugs, especially on Switchback where the elevation changes sometimes mess up the grip calculations. I am planning to add support for custom UI themes in the next update. Feedback is highly appreciated!

This is exactly what the community needed. Those sudden fog transitions in career mode used to ruin my runs. Since you are already pulling tire data, would it be possible to add a degradation multiplier for tire wear? Having the grip coefficient adjust dynamically as the tires wear down in wet conditions would make this the ultimate telemetry tool.

So you're telling me I can't blame invisible ice patches for my terrible fog-driving anymore? Way to ruin my favorite excuse in front of my crew.

This script is a game-changer for career mode. Actually seeing how my tire upgrades handle the shift from sunny to foggy in real-time takes away all the frustrating guesswork. Thanks for sharing this Tampermonkey overlay!

This is exactly what career mode has been missing. The sudden transition from sunny to foggy always ruins my setups because the visual cues in this game don't match the actual physics engine. Could you add track surface temperature to the telemetry calculation next? That would make this script absolute gold for the longer endurance races where track heat fluctuates.

So you are telling me I can no longer blame my terrible spin-outs on unexpected fog physics? Thanks for ruining my favorite excuse with your fancy telemetry script. My virtual mechanics thank you, though.

So you are telling me you do not enjoy the pure adrenaline of guessing if you will slide into the barrier at the next foggy turn? Where is the fun in actually knowing your grip? Seriously though, my virtual mechanic thanks you.

Calculating the grip drop during foggy transitions was pure guesswork before this. Having your telemetry overlay factor in my tire and nitro upgrades in real-time is going to save my career mode runs. Installing this Tampermonkey script immediately!

This saves so much trial and error during those sudden mid-race downpours. I tested it on the Alpine course and it works perfectly. Any chance you could add track surface temperature to the telemetry calculations? That would help us predict exactly when the racing line starts drying out.

While I appreciate the effort put into making this script, I feel that showing the exact grip coefficients takes away from the core challenge. Part of the fun in RacingGame is learning to read the track and adapt to weather transitions by feel. Having a real-time overlay makes it feel a bit too arcade-like and removes the skill involved in managing unpredictable track conditions.

Does this script work in multiplayer lobbies too, or will the game's anti-cheat flag the UI injection? Also, does your formula account for dynamic track drying lines, or is it just a flat coefficient based on the general weather state?
