I saw this video on Instagram a few days ago and I can't seem to find any response to identifying this game. It doesn't seem to have any identifiable HUDs. I'm not even sure if it is a racing game or a modded game.
I believe this is the game called The Crew. In this game, your drive across all of America (it's a fairly large map and it's also misshapen some), so you can encounter snowy regions like this. It is similar to Forza Horizon.
The way I can tell is if you look closely at the video, you'll see around the edge of the screen a bunch of arrows moving around that indicate other players in the game. This is the biggest indicator of the game. Take a look at this screenshot:
I've circled the the arrows. The screenshot was pulled from this video. Here is a screenshot from your video with the arrows also circled:
Other things as evidence is I believe the car being driven is a Ferrari 458. It has a twin exhaust which you can make out in your video (circled in the screenshot):
As you can see in the below screenshot, it shows the exhaust (as well as the other similar body features):
