What are features of Google Maps' 'biggest' navigation upgrade in a decade?

'Immersive Navigation', which integrates Gemini AI with Google Maps, redesigns the visuals into a 3D view for navigation with real-world information, Google stated. It highlights road details such as lanes, traffic lights, overpasses, etc, and can also help recommend parking spots at a person's destination. CEO Sundar Pichai called it the firm's "biggest navigation upgrade in over a decade".
