There are a few things that people forget.
We are either sitting on the left side of the car or right side of the car, and not in the middle. So our line of sight in city driving is not always directly ahead of the driver.
And people just assume that center screen would require you to take your eyes further away from the road than traditional instrument panel, and my conclusion is that this is not true.
I believe the Left Upper Corner of the center screen is closer to your line of sight during city driving than traditional instrument panel.
And I don't know about you, I look at the center mirror and side mirrors
way more often when I drive than my instrument panel and center/navigation screen, and they are way off the line of sight. I don't feel any less safe while checking my mirrors.
So instead of writing it off, you should test drive what Tesla has to offer for a single screen design before making your decision.
