Driver side dash as you call it I would rank in the middle for convenience. There is also some convenience in having certain controls like sound and climate accessible by the front passenger, so most are driver side plus middle, but I’m accounting for that in my ranking. Even with that, still in the middle.
At the top of the convenience scale would be a hybrid system with minimal multi-axis, multi-function buttons situated on or around the steering wheel, augmented by a touch screen for rarely used features. And for display. A screen that is not blocked by the steering wheel no matter what your height. And a screen robustly mounted so you can rest your hand on it while making selections, so any road shaking is mitigated. A screen big enough to read easily. A screen that never needs to be interacted with for most driving functions with the exception of tweaking the way the car is currently doing autopilot when it is. And a screen that lets a front passenger reach controls that are safe and useful for the passenger to use. That is the kind of system the Model 3 has. Not just a touch screen.
If it’s convenience you’re after, driver side dash may be more convenient than your perception of the Tesla. But your perception is wrong, based just on what you have just said.
I recommend to everyone that they test drive a Model 3 in order to feel how it drives, and feel how tight the control is, the driver’s connection between the wheel and the road. I don’t know how long your test drive was, but a test drive is generally too short to understand the full functionality of the easily accessible steering wheel multi-axis button controls and how driving works day to day in all situations.
