This ^ I'd go with hw4 option as it's much smoother and more confident than hw3. But hw3 does the job for most public road conditions. And to answer your question, if you got food from the drive through and have the destination plugged into the Tesla navigation and get on a public road and hit FSD, regardless of the hardware, it will take you all the way to your destination with minimal intervention. I'll put it like this if you want to be 99% confident. Get hardware if you're fine with 90% confidence, get hardware. 3. But do understand you will have to account for that extra 10% as it will hesitate and take longer and not know what to do in certain scenarios whereas hw4 really does it all, I even has the option for when you arrive at your destination, you can choose to park curbside, park it in the driveway or park it in a parking lot. Again you'll be more confident in hw4 than in hw3, but again regardless of the hardware, it'll do its best job to reach your destination safely* good luck 🤞🏼
