I was thinking the same, do my daily trip and wait for a better game. I wonder how all these people, who are grinding for days, are going to feel when they add new menubooks and it turns out that they just give you a CLK-GTR or Porsche GT1 for completing a VGT collection or something like that...

I saw a leaked promotional photo on the internet purportedly of the GR Corolla.
The car looks as if Toyota made the GRB WRX. Definitely one of the wildest hot hatches of the modern era.
PD has a friendly relationship with many Japanese brands like Toyota and Nissan and tends to add their latest models to the game very quickly.
The GR Corolla will probably be in the game within a few months. Can't wait.

The RT isn't low-res at all, the nature of how RT works will always result in something easily higher-res and have more accurate detail than cube maps. Low-quality RT would result in noticeable dithering that takes more time to resolve, but there's a decent denoising solution being used here. However, sometimes you can see large dither artifacts when a car's paint job has more diffuse reflections due to its rough surface rather than mirror-like reflections which are much less taxing to trace. For rough diffuse reflections the rays are being reflected at many different angles and there's isn't any cheap way to simulate this.
In your example, all of the trees being ray-traced are of simplified geometry in the reflection to save on resources (there's much less alpha cards for the trees canopies), the actual RT reflections themselves are still higher res than the cube maps. It's a smart optimization method for a $500 machine doing RT.

I forgot about the achievement regarding buying 10 if the same car. Maybe I can buy 10 ae86 Truenos or something. I know that I have 3 if the darn things.

Actually this is not 100% true, the real time RT effects are much much lower quality than the cubemaps. They only look higher res when you look at them in photomode. And even then they miss lots of the stuff in the environment that the cubemaps do reflect and are less stable like you said on softer reflections. Don't get me wrong the RT in photomode is still one of the best ever used in a racing game but it still has too many flaws and looks horrible sometimes.The RT isn't low-res at all, the nature of how RT works will always result in something easily higher-res and have more accurate detail than cube maps.

Here i have some examples.
look at the missing signs, orange warning lights, bariers and orange truck missing in the rendered RT shot.

And they look terrible when there is a rough metalic material even when you render it at higher resolution.

And this is how it looks in real time on a chrome car, just low resolution and unfiltered.
little edit: Here is the non RT version in real time in the GT auto, look how much sharper and better it looks compared to RT version.

For those who want can make comparisons with the 1.00 compared to the current one, after the downgrade of the effects received in the 1.06, I suspect that they have also lowered the quality of ray tracing.Actually this is not 100% true, the real time RT effects are much much lower quality than the cubemaps. They only look higher res when you look at them in photomode.

The BOP default tune on the Ford GT race car 18' is so bad. I say this as a warning. Don't choose this car if tuning/setups is not on.
Never been so happy with a P13, best GT driver in my race lobby at Nurburgring 24, Manufacturers Cup test season 2 rd.1. One of the hardest races I have ever done. I'd take a wet Spa, Le Mans or Red Bull Ring over this everytime.
PD needs to fix this. I knew I took a risk with Ford. But daily b interlagos last week was not super bad with this car, although most of the other cars were faster. So I am surprised with it being this bad. But anyways, car control skills improved after that one for sure..

The environments aren't using ray-traced reflections in photomode as the car body parts. Looks like they're using something like signed distance fields to get more accurate rough looking reflections for certain objects and lights. It can be a bit weird looking though.Actually this is not 100% true, the real time RT effects are much much lower quality than the cubemaps.

And RT reflections don't look higher-res only when viewed in photomode, as even in replays and free cam they are higher res than the game's cube maps. The way cube maps are designed is they are only accurate for a single point in space, so they will never be as accurate as RT, and sometimes you'll probably even see things that shouldn't be there.

The "chrome" color you're using isn't a good example since that actually looks to use more of a diffuse and rough material (the point is to create more blurry reflections instead of mirror-like reflections), which also goes back to the dithering artifacts from the RT reflection being more taxing in that process with diffuse materials, it's scattering rays in multiple directions to achieve the rough look. Here is a normal color and doesn't look "low-res".

I wish they included some other interior options; like the blue plaid interiors, the dark brown/caramel leather, or blue leather, white leather, etc.

Look at the bariers and the buildings, and look at the stuff missing in the RT version

Here you can see the car even reflecting in the barier

Also the RT reflections are lower quality in motion and have no filtering, so when you stand still it will look good but the moment there is a bit motion everything turns grainy and low quality. And its not only on the chrome paintjob that it looks bad, it looks like that on all the colors but on chrome its easier to notice because it acts like a mirror. Here some more examples with different colors and cars.

They just need to drop RT from GT Auto, because it looks amateur as hell compared to Horizon 5's Forzavista equivalent.

FH5 only reflects the car onto itself anyway. If you open a door and look at the reflection while moving around a bit, you can see the RT reflected tire being disconnected from the cubemap reflected ground. The environment reflection is also pretty low quality, at least outside houses.
Still though, at least the reflections aren't blurry and weird.
