Good read and a nice reminder, thanks for posting. I remember reading those articles when they came out and how they added to my excitement for the model 3. I have not cancelled and probably won't until I at least get to drive the car, but the S4 is still probably happening.
There are a couple things weighing on my mind when it comes to the Model 3 and each alone is not that big of a deal, but in total they are stacking up. I have serious concerns around product quality of a new design and new car by an inexperienced manufacturer at this scale. I strongly believe they will fix whatever the issues are and long term it will not be a problem, just not sure I want to pay to be along for the ride anymore. Also, it feels like they are very behind on scaling production and I don't trust the Dec to Feb timeline. Another is that after driving the Volvo XC90 which relies on a touch screen for a lot of controls, I am not sure I want even more pushed to the screen. And the weirdest one is actually my biggest pet peeve, the wiper controls. I adjust the speed often during a rain storm and I don't want to use the touch screen for that either.
Because of how I was feeling I decided to look for a back up car. Someone I would get if I decided to not buy the model 3 after driving it. I found the S4 and fell in love with the car. We didn't mean for it to happen ;-)
I am keeping my deposit with Tesla for the time being and won't move forward until December on the S4 (year to remember event) so there is still some time, but all things are point to 4 rings in my future.
