A couple from Wisconsin made their first long-distance trip in a 2026 Model Y with Full Self-Driving Supervised V14.3.12, covering about 1,500 miles from Northern Wisconsin to Northern Utah. After a total loss of their 2019 Model 3 in an accident in May, this was their first road trip in the new vehicle. Near Wausau, the navigation rerouted around a closed exit, adding roughly 5 miles; the system knows about closures and traffic jams but does not explain the route change in advance. At the Wausau Supercharger, all eight stalls were full for the first time in seven years.…

2026 Model Y with FSD Supervised V14.3.12 on a trip of about 1,500 miles.
Wausau Supercharger: 8 stalls full; shared charging at 50 kW, about 40 minutes.
Menomonie Supercharger with Hardware 4: almost 100 kW for the whole charge.

🔎 Why it matters: It is a firsthand account of a 2026 Model Y running FSD Supervised V14.3.12 on a trip of about 1,500 miles. It documents the detour around a closed exit in Wausau and charging differences by Supercharger hardware: V2 at 50 kW versus Hardware 4 at almost 100 kW.

📈 Upside: In Menomonie, the Hardware 4 Supercharger charged at almost 100 kW for the entire session, nearly double the V2 charger in Wausau.

📉 Risk: The navigation took a detour around a closed exit in Wausau without explaining the reason in advance, which cost roughly 5 extra miles.
