Current EV trip planners optimize for maximum range, not accounting for the unique needs of cars like the Roadster that can charge extremely quickly but have shorter range at high speeds.
Create a web app that plans routes based on 350kW+ charging stations and models optimal stop durations for different driving styles. Include real-time status of high-power chargers.
Initial version could use existing charging network APIs with Roadster-specific routing logic. Later add user-submitted reviews of charger locations.
Risk is that Tesla may build this directly into their navigation system.
