You can say that about the Model S and Model X too. After five years on the road, Model S users are still getting updates with new features and performance enhancements. Pretty nice, if you ask me. Heck - GM couldn't even be bothered to give 2016 Volt owners the 2017 energy rating display when we all took our cars in to the dealer for various firmware recalls last year.
I checked out my neighbors Model 3 a couple of days ago. He was even kind enough to let me drive it for a few miles. His is a very early car. Not first 30, but close. Fit and finish looked fine. Drove like a dream. Yes, there are a number of hardware bits that don't have software support - for example the interior camera above the rear view mirror. But that will come in time. As it is, the car is quite driveable. Wifi and (free) LTE access is built-in to the car, so updates are easily done without taking it to the service center.
