Seatbelt ticket
Son-in-law was pulled over, Pickens County SC, couple months ago. 2 adults and 3 teenagers in the car, not one wearing a belt. The 3 that held a drivers license got 25 dollar fine each. Not nearly enough in my opinion.
I agree that your early belt design is a spider web of freakin belts to hook up but... son-in-law, my daughter, and my grandkids in 200? Camry, no excuse... and I told him so.
Same laws apply to all for good reason. Want to drive a classic today, wear your classic belts.
