Let X = the number of people saved by use of a knife
Let Y = the number of people injured or killed by a knife
Do you really think that X is higher than Y? I'll bet Y is two orders of magnitude higher than X, at least.
Does this mean that we should make the very existence of knives illegal?
Of course not!
This isn't an issue of saving lives, it's an issue of communist-style government control. If they can put a number behind a policy that makes it seem like you're better off with the policy, regardless of the facts, they'll do it over and over again until we find ourselves getting shipped off to labor camps because of an off-color tweet.
Just a couple situations where this policy would absolutely suck:
- Obvious "stuck in the car" scenario
- Car breaks down on a busy highway. Nearby cars will almost absolutely block your signal. You'll have to walk down the highway until you can exit on foot, or else your call will drop every time someone drives by.
- Passenger needs to make a call. Now you have to pull over, get out, and hope you can get far enough from your car and other traffic to keep your signal from getting blocked
- I use my phone GPS. While blocked, I would have to print out directions, which makes me have to read them while I'm driving. With my phone, I just set it, look over the route once to make sure it isn't insane, and follow what it speaks. No distraction... unless I need to look at a piece of paper...
A distracted driver is a distracted driver no matter if they're on the phone or doing something else. It would make more sense to outlaw putting a radio and cd players in cars, and while we're at it let's take out a/c because drivers get distracted while operating the controls. Best of all, nobody can be killed by lack of music. Let's take it a step further and mandate all cars look exactly the same so drivers aren't distracted when the Lamborghini drives by. Nobody will be hurt by that one.
My point is that such a law is absolutely, 100% stupid. If you want communist control, go to China and stay there, please.
