heh, thats exactly what happened to my in the Prelude. Traffic stopped suddenly and as soon as I got stopped I looked up in the rear view and saw F-250 grille coming at me with what in a split second became obvious to me was no intention of stopping or slowing down. It took me at least a year to get over stopping short and instantly looking to the rear view and having your heart drop if you even saw there was a car in close proximity.
Probably gonna take a long time for that feeling to go away. I got rearended a couple years ago (not even bad…no damage or anything!) and I still watch my rearview for someone who looks like they arent going to stop. Im not nearly as bad as I was, but its been like 4 years. Glad you are okay!
