There was a death at 20mph around our area though, because of no seatbelt. It was specifically shown at the course to attain the driver's license.
The same person who's super disciplined about seat belts likely takes other risks that another person would deem at least as serious.
Having an optional reminder feature is great; forcing it, not so much.
Doesn't take much FOD on the highway for your unbuckled body to slam into something and now you have a driverless vehicle. Also every else in your car should be bucked too so you're not bumping noggins.
Is this how far you're willing to go to boss other people around to fit your preferences?
Or is it just the job of the survivors or your bullshit to sue your estate into non-existence?
