What would you think of making this a required safety feature?

We have mandatory drivers education classes but no mandatory gun education classes.

Now there's a good idea.

Making guns less safe for me with this "safety feature" makes less sense than an education program.

Unless you're a very forgetful ninja, you probably aren't in dangerous situations often enough that the scenarios you've posed are a real risk for you. Besides, given how much you seemingly focus on your guns, chances are you'll just kind of have the wristband, plus the first hacking solution available around at all times, so you can turn it back on at any given moment.
