I’ll put my hand up and admit I used to mount my mobile phone (for Google Maps) in the middle. I’m tall and it got mounted low down. I personally didn’t feel it obstructed the view but I moved it when recently on a Driver Awareness Course (ahem) the guy said this was a definite no no and you could get pulled for it.
So it got moved to the right by the driver side pillar and I agree with a previous poster that it seems more obstructive there. And slightly more distracting when you glance that way for directions.
That said I was following some crazy* woman this morning who had her Sat Nav mounted slight driver side underneath rear view mirror. How the hell that ISN’T obstructing I’ll never know!
*stuck behind a tractor for all of 5 mins this morning 3 aborted passes before it was finally safe to pass, she gave the tractor driver a trailer full of car horn and middle finger. I followed, road was clear we got up to 60 and she decided to brake test me.
Hoping I don’t meet her on the road when I’m out on my bike.
