I was recently browsing sites that offer car-mounts for my phone and I came across one from a company called 'Studio Proper'. The mount looks awesome but their promo video advertises the absolute worst location for a phone mount that you could imagine. In the video, they have it at eye-level, just a little off-centre from the steering wheel. Seriously - check it out for yourself here : https://vimeo.com/113662097
I know in places like California it's against the law to have anything mounted to your windscreen, but what they show in that video is just irresponsible. From the driver's point of view, yeah - great access to the phone. But it comes at the expense of being able to see anything out the right side of the windscreen. At one point in the video you even see a pedestrian disappear behind the phone because of it's location in the car.
The sad thing is I see people mount their phones and GPS's like this all the time, and it amazes me how they haven't the common sense to realise how dangerous they're being when doing this. But to see a company selling a phone mount and doing this bad a job with their PR video was a real facepalm moment for me.
