This is exactly the kind of argument I tried my best to prevent when I said that we already have speed limitation both on the society level and on individual one. You may rise the bar for the amount of training required for children in the US, you may restrict the speed capacity of the vehicles they'd be allowed to drive, you may disallow them to enter the kitchen for the fear of knives that they might find in there, you may even keep them in the leash until you'll deem them ready for the world out there (if ever), there are a lot of options that would address the problem a more localized manner instead of some global restriction "just in case". I'm not talking about the specific limit Volvo has chosen for their cars, because for the most part, the specs of the cars they make are theirs to decide, after all. What I'm talking about is an automaker promoting speed limiting as necessary for safety and about the voices that endorse that as reasonable. If the safety indeed requires an improvement through additional speed limitation, that would have been addressed by the bodies of society whose job is exactly that public safety, and by further adjustment of our driving speed on the individual level, considering the self-preservation instincts (which are supposed to checked along with the rest of one's mental condition prior granting the driving license).
