Need routes based on cost (and charge speeds)

I’d buy premium if I could plan based on cost (based on a minimum charging speed).

Better would be ability to add planned meal/errand/sleep/stop(s) with slower min speeds (totally worth it if I could save). Most trips I want a minimum of 100kw or 150kw charging, but slower is worth it on long trips where I could plan to enjoy my time to eat/sleep/shop/visit while my car charges cheaply.

Save me $$$ and I could afford premium!! That’s a personal ROI
