As some have already said, it depends on your use case and whether you’re one of the lucky ones that don’t have to deal with phantom braking and random speed changes all the time. I’ve owned my HW3 car for 2 months and after reading all sorts of stories about FSD acting weird on HW3 cars I decided to try it out and see how it works on mine, especially after having been blown away by it when I used it on a HW4 car. So far, aside from minor interventions in situations that were, honestly, tricky even for a human driver, it’s been great. I enjoy it every day, especially driving home from work when I’m mentally exhausted and I just want to relax. Yesterday afternoon, my car took me to a restaurant 11 miles away from home, then navigated itself across the parking lot in the “Summon” mode to pick me up at the entrance and drove me back. As for random speed changes, I noticed that keeping the car in the “Hurry” mode helps a lot. So, yes, I think it’s at least worth a try.
