What aspects of Zwifts virtual environment do you think are the most immersive, and conversely, what elements detract from the overall experience, making it feel more like a simulation than real-world cycling? Are the virtual routes and courses engaging enough to keep users motivated, or do they eventually become repetitive and stale? How does Zwifts implementation of real-world physics and weather conditions impact the perceived realism of the environment, and are there any notable omissions or oversimplifications that take away from the experience? Do the social features, such as group rides and events, enhance the virtual environment, or do they create distractions that detract from individual performance and progress tracking? Are there any missing features or improvements that would significantly enhance the virtual environment and overall user experience?
