Roadside grip

The roadsides in the game aren't realistic; they should have much less grip than the track. This is due to the painted asphalt. In real F1, drivers rarely use the roadside, but in the game, they do so frequently.

The same applies to medium-sized kerbs. In real F1, they are avoided by drivers (like tall ones), but in the game, they can be driven over without affecting the car (e.g., the second corner of the chicane in Australia can be driven aggressively in the game, but in real F1, it's avoided).

In addition to curbs, some tracks also use artificial grass or other low-grip surfaces (often painted) placed directly behind the curbs to further discourage drivers from leaving the asphalt portion of the track. 

Change this! Add realism to the game.
