Real-World Takeaways: Tesla HW4 and FSD V14 in a 2026 Model Y

Over two weeks with HW4 and FSD V14 in a 2026 Model Y, the author reports major progress: FSD V14 can start trips, back out of driveways, and navigate with modes from Sloth to Mad Max, effectively acting as a chauffeur while requiring supervision. GPS/map accuracy remains a bottleneck (about 15 feet) with occasional misdirections and parking challenges, especially in garages or lots. The system relies on visible-light cameras (no radar), won’t handle severe weather well, and steering assist requires a $99/month subscription. There are several features still on the wishlist. Overall, notable improvement, but not fully hands-off autonomy yet.
