What specific features do you think would make the undersea tunnels on Zwift a more immersive and realistic experience, considering that some riders have complained about the lack of realistic water visuals and the need for more engaging sounds and interactions while navigating these sections? How do you envision the ideal representation of the ocean environment in terms of visual details, like fish swimming alongside or even in front of your avatar, waves crashing, or other oceanic features that could make the experience more engaging? Should these undersea tunnels be used as a key feature for specific events or Training Plans, or do you believe they should be left as a novelty to keep the rides fresh? Is there a specific length or complexity youd like to see for these undersea tunnels, and how do you balance the need for realism with the need to keep the experience enjoyable for all riders?
