It's amazing to me that Tesla is able to sell a car in its price range that lacks basic features that come standard on a $17k Corolla like adaptive cruise or automatic emergency breaking, especially since they effectively reduced the capabilities of their cars by rolling out AP2. If any other company tried to pull that, they'd be laughed out of the room, but somehow, Tesla is cheered.
You've clearly never driven a telsa if you think a $17k Corolla has more advanced adaptive cruise control. I've driven my model S over 15,000 miles, with probably over 50% of that on autopilot (mainly interstates), and NEVER had an issue with the adaptive cruise control. Its absolutely flawless. (autopilot has its quirks, although its still an extremely useful feature, and the primary reason I bought a tesla)
