Several years ago I lived in Mexico, a lovely country ruined by a simple feel-good safety measure that has destroyed the beauty of the country. Topes are the curse of the Aztecs, what probably started as a simple local idea has become a national way of life, they're everywhere. Topes are speed bumps and of course if one is good, then a bigger one is better and 3 are even better and it grows from there. You cannot drive through the country enjoying the scenery because you have to be intently watching the road 50 feet in front of you to prevent ripping out your suspension, damaging a tire/rim and at the very least jarring your brain. Topes are a cottage industry created by every man who gets elected to office and can mandate some new ones be built and the contract always goes to a brother-in-law, a cousin, uncle, you name it, it's a money maker and a power extension of high office.
We used to debate these insidious creations on a local forum. The whine was that they save lives, I said prove it, show me one person alive today that would be dead if the Tope wasn't built and of course you can't prove that. But, I can prove they are dangerous. I lived at Lake Chapala 35 miles S of Guadalajara and on the weekends the "Tapatios" as Guad residents call themselves come down to the lake to play. Coming into Chapala is a long sloping hill where no doubt the drunk drivers were speeding on a Saturday night. But, everyone living there knew it and kept away or was aware of the potential for disaster and to my knowledge nothing ever happened in the seven years I lived there. But, one day there were suddenly eleven topes on the incoming stretch before the stop light and it was no time at all before the accidents started and then a death of two from drivers losing control. So, the topes saved no one, but killed several. Finally they did take out every other one. The lesson learned: good intentions do not guarantee success, you can't prove masks or shots saved a single life, you can speculate all you want, but experience is growing as to the detrimental affects of this whole charade that is documented.
Masks and shots are nothing more than a sign of political obedience, the only people wearing masks outside are neurotic or zealots.
