We love the BeBop USA car harness that I bought after reading posts here. It lets my small dog (18 pounds) look out the window and he can easily lay down and sleep in the back (something he never did when he was riding in the front seat/on my lap). According to the BeBop site, the setup was designed by veterinarians and orthopedic surgeons to be anatomically correct, to avoid tracheal injury or damage and other potentially fatal injuries. And from the posts I read before, BeBop had said the strength of the 3/4" is 2800 pounds and the 1" is 3200 pounds. There is no plastic hardware to break as the strap connects to two steel d rings on the harness. We also were able to call and order and additional car strap for my boyfriend's car so he can ride in either (just need the one harness).
