My significant other has a new (since May) Tesla MY. We took our first road trip (AZ to TN to WI and back) which covered 4500 miles. I purchased the FSD subscription for the trip. My initial results were mixed. I would never pay $10,000 for the FSD package as it stands or even the $200 monthly subscription fee. Glad I was able to try it first. I will admit, it has potential. First off, it would just apply the brakes when in randomly when in FSD, even though there was no traffic. Also the nag screen became a nuisance. I will say that driving through the mountains at night was very convenient as it followed the road flawlessly. All in all, I think when it's working right, it has merit but I believe they have a ways to go.
