I like the horse collar. When I had a D/SP 77 Civic there was the benefit of a serious rally seat, four point roll bar, and four point belt system. I did not get IN the Civic, but rather WORE the Civic. Sort of like putting on shoes. For a couple years I did not wear the collar. Last year I started wearing it again. And this year, I am wearing volleyball knee pads. My head is more stable, and my legs do not feel all the banging about in the car. I do use a G-Lock seat belt lock. If I could use a four point harness I would, but installing a roll bar is out of the question. With my head stabilized, my fat ass cinched up in the seat, and my knees not feeling the hard plastic, there are fewer distractions. Better.
