Can you Road Trip in an EV without planning in Europe?

We decided to do a European road trip this summer with the kids and without any planning! All we knew was we had a 1 way Eurotunnel ticket and the first night booked near Dijon in France. That was it.
I have made references to lots of the data found in A Better Route Planner, an App specifically designed to help you plan a trip like this. We used it during the trip where we might need to arrive with more charge than the car suggested, but not before we left.

The route took us through France, Monaco, Italy, Austria and Switzerland from the U.K.

What would it cost? Were would we end up? Would we make it or get stranded?

If you want to get involved we have a community discord available for patreons now!
