Are our Slants "Unsafe"?

Jeeze, I've never seen a Pinto crash test, thats scary. I've only had one accident with another car pulled out on a illegal left hand turn and was not enough time for me to react, locked up my 1962 Tbirds breaks and slid into the new car and ripped there front end off and my chest smacked the steering wheel that hurt but the Thunderbird was fine just a scratch, my car had no seat belts but after that I installed lap belts.
I rather be in a old heavy car or truck and win the battle but must have lap belts now after that experience.
