Twentieth Question for President Biden

Mr. Biden, if the countries of the planet got together and instituted a world-wide 20 mile per hour speed limit, we could probably save 1,000,000 lives a year (1.3 million die every year from road fatalities and you have to think that at least 80% of those lives could be saved with a huge decrease in the speed limit) and yet no sane individual has ever proposed such a thing because they know that commerce would be stymied and many more people would die because of that. And so my question is, why have not you and the rest of the political geniuses of the world been able to make the same calculation when it comes to COVID (the lockdowns having caused far more suffering than the damned virus)?
