I always enjoyed how water puddle reflections create kind of immersion on road surface, the problem for me was, they form too slow, even on fast multiplier times, also they wait the track wetness become %100 to begin forming. Another issue for me was, you need high rain intensity for this and the rain particle effects of high rain intensities looks bit bad (beyond %30), %2-10 seems nice enough for my perception of realism.
Anyway to solve this, I modified the controller.lua file. Now, after couple of minutes, the road becomes full reflective. You just need small intensity values (2-10). I want to share the file here if anyone interested;

You need to put controller.lua into assettocorsa/extension/weather-controllers/sol2 folder
I also put my sol configuration file which I made some tweaks if anyone wants.
it goes into documents/AssettoCorsa/cfg/sol
Please backup these files originals first.
