Does GM have some phobia about center headrests? On a $40,000 multipassenger vehicle, why do the outboard passengers only have headrests? Even on my 10 year old Volvo and BMW, I have them. A brand new Caddy CTS across the street lacks them. I understand the center one can be a visual barrier, but have it push down flush with the seat! Call me a safety nut, but I think this is a major oversight. I wonder if it can be added on by the dealer for a reasonable price?? Does anyone else have this concern?
