That's funny... sure seems like a lot of work just to kill a seatbelt buzzer that you might hear for a couple seconds! Guess I was raised with the habit of clicking-in before I start the engine (unless it was a cold day and it had to warm up first).
Back in the day, we had bench seats, so if you didn't buckle up, you'd be sliding around corners!
Guess I'm really showing my age now!
