In the car designer, left side where the stats are.
The two boxes showing the top two markets should have an indicator of some sort to show if they improved or not like all the other stats.

I suggest to turn the color of the text red if the ratings drop and green if they improve, not sure if the colors will clash since the background color can vary.
Another possibility is to use an up and down arrow beside the numbers.

Yes, that will probably make its way into the game with the next big update.

Is it also possible to make the indicators visible in the car tab (first one out of the three)? Things like body panel material strongly affect safety, would be nice to see if plastic panels fail safety requirements for example.

That is a good point, not quite as easy to do because of how the car designer works though. Definitely something we want to have later when remaking the UI and flow in Unreal Engine.

I was wondering if it make sense the following: create an option to see the market stats, not just for a chosen market, but for all the markets? Like average stats of all markets? I think that way would be more easier to build an average car that fits all markets.

I think that may be too misleading? I can see a top 10 average to work in cases you want to make a generic car though.
