My wife's throat impacted the 68's padded dash. It almost killed her a lot. Her throat swelled up and she had to be intubated on site.
Don't fool yourself into thinking that direct impacts with plastic covered sheet metal surfaces such as dashes, doors, and A-pillars are
any safer than properly placed roll bar tubing with the
correct padding and five point harnesses.
I re-engineered the seat brackets to lower the seats for adequate clearance and we ALWAYS wear the five point harnesses to resist vertical movement.
Needlepoint is dangerous also. Those needles are sharp and the yarn might accidentally get wrapped around your fingers and interrupt circulation.
