reflaction and blurr and distortion required..
mostly reflaction earn by render cars flip down by road surface.
and you can blur( or low resolution ) and distortion by shader distortion can earn by sin, cos function or some texture map's offset.
It's not hard to do
and realistic scene need very detail gesture.
how about wave about raindrop at road
I sujest that kind of gesture or water wave by tires
It can acheive by dynamic texture of distortion .
if you need deeper opinion I will descripe it more
Thank you for your response.
Requesting you for more description of the same.
I must clear about how much you understand but...
I just tell the brief..
and I think you are very familiar with reflection.. flip car and render at road side. you can render that car to new texture with low resolution..
and you can distort it with sin or cos curve.
this is basic thing to do.
next you can render tire trail to road in new texture buffer and tire tail must vague by time
so you have texture with tire trail..
with tire trail texture you can distort water mark or normal or water surface
so you have flipped low resolution car image and wave term by sin or cos (or anything) and tire thread's power on the road
so you can composite final scene with this you can add flipped car for mirror image and distort it with term and you can distort it more with tire tread and you can add specular on tire tail..
I'm not good at English but I try to explain about it.
Hmm.. I worry how much knew about reflection and shader and post processing..
