I'm not sure how easy this would be, but electric vehicle integration would be a perfect feature for Kagi Maps in my opinion. The best option for planning routes is A Better Router Planner (ABRP), which offers EV integration with a subscription. However, ABRP is lacking in the actual maps department. If Kagi could implement an EV integration to actually track your battery percentage and find chargers along your route, it would be the perfect map companion. It would make a Kagi Ultimate subscription very much worth every penny and would immediately be able to compete with Google/Apple Maps with features not readily available on their platforms.
Users would be able to map road trips and find chargers for their EV along their route, all while tracking their actual battery percentage and expected range for the best accuracy and results.
