A mandatory warning is part of the law, but actual restriction is not, so
should you be in those occasional situations where breaking the speed limit is
safer than following it, you can (usually, depending on your manufacturer) just
keep the foot on the accelerator despite the alarm.

Apart from things like seatbelt laws, high taxes on tobacco, enforced rules on
food safety, regulation of medication? Or are you completely fine with easily
avoidable death and major disability, shorter and worse-quality lives, mass
poisonings, more mass poisonings? The middle option saves on taxes given if you
die at 63 from lung cancer you won’t draw much in the way of state pension, so
there is a financial but not humanitarian argument for it. There’s no argument
for the rest.
