If you don't have HW3 you won't see the visualization options in the "Autopilot" menu. The visualizations are only for HW3-enabled cars.
Purchasing FSD will eventually get you the hardware (for free) but other than this visualization there's no real practical benefit yet.
Edit: I'm seeing a lot of threads assuming that the purchase date implies HW3. It doesn't. I have a June 2019 car with HW2.5. The practical upshot here is that this is the first update that will allow us to know what hardware we have, since prior to this update the only way to know was by ripping apart the panel under the glovebox and looking at the CPU part number itself. Now it's simple - if you don't have the option in Autopilot, you don't have HW3.
Yeah that's what I figured. I assumed I had HW3 due to manufacturing date (based on everything I had read) but the fact that I don't have the option likely means I'm on 2.5?
