———————————————————————————
If I plan a round trip from Ede, Netherlands to Thionville, France with an MG ZS EV 2021 SR, ABRP advices a route through Germany for both directions. If I leave on April 20, 2024 3:30 AM, I'd arrive in Thionville (Gare) at 9:21 AM and I'd be back in Ede at 15:23. If instead I add an intermediate charge stop at Fastned Baraque de Fraiture in Belgium, I'd arrive in Thionville at 8:35. I'd then be back in Ede at 14:08 with ABRP's default 4 minute stop in Thionville. So the route through Belgium is clearly faster. Why then does ABRP keep advising me to drive through Germany? I've had the same issue in previous drives to several locations at the eastern border of Luxembourg and all those times, the route through Belgium turned out to be faster.
