The current position of the speedometer is a poor excuse for moving it
further from where the driver’s attention should be: the road. The distance and context of where the driver information is displayed matters a lot.
My car has its entertainment display roughly where the display is on a model 3. I can tell you that looking at the speedometer is much much quicker than glancing over to the screen in the middle. Probably by an order of magnitude or two. Even checking the clock takes a dangerous amount of time compared to checking my current speed, the difference is that drastic.
Further more, the instrument cluster is designed specifically to be easy to read and driver oriented, Porsche’s habit of putting the tachometer in the middle comes to mind. The center console has to support many more activities, including entertainment, and is thus much more distracting by design. This is true on my car, and the center screen is much simpler than a model 3.
HUDs aren’t exactly exotic supercar material these days. The Honda Accord Touring (MSRP $33k) has one standard. Now that’s the top level trim for that model, but it’s also in a much lower market segment than the model 3.
