Hi,
on the Tesla website there is just one location listed with 12 stalls. In fact it’s two locations, one at Dorno Ovest (direction Milano - Genova), the other one at Dorno Est (Genova - Milano). 6 stalls (among which 2 CCS) on each side.
At Google Maps these are displayed correctly, the Tesla navigation has it right as well.
But e. g. Abetterrouteplaner does not calculate in S-N direction correctly as you cannot access the west location (autostrada with separated lanes) without a 41 km detour.
Please update.
