Pop down to your local $2 shop and buy a "$2" (in reality about $10) suction mount phone holder with a similar size suction device to the better quality one you are thinking of buying.
Whilst stationary on the ground (obviously!) test it on various parts of the inside of the curved glass to get an indication of whether and where it will work.
Having done your research, give it to the next driver you see clutching their phone to their ear at the traffic lights.
