The 'Grand Prix' mode allows you to create custom race weekends. You can choose any track, any F1 team and driver, and customize race length, weather conditions, and AI difficulty. This is an excellent mode for practicing specific tracks, trying out different car setups, or simply enjoying a quick race without the career mode's long-term commitments. It's also a great way to experiment with different strategies or test your skills against specific AI levels before tackling them in career mode.
