This is one of the allures of Forza Horizon for me. On the surface, it's an MMRPG, with social, collection, crafting, levels, puzzles, competition, et al, all of that can be turned off / ignored as desired.

With those items off, it's a great place to "drive" around, with different climates, seasons, amazing views, etc. Drive a classic convertible along a beachfront road. Explore dirt roads in an SUV during a snow storm.

It's no driving simulator, but it's a pleasant way to get away from the world for a while. If you've got the winter blahs and like driving / scenery, plug your PC or Xbox into the biggest display you have and get away for a while.
