Heh. I'm all for dangerous stuff around kids, but walkers are just dumb to begin with. Why the hell do you want to put your kid into a contraption that prevents it from falling over when it goes too fast? The walker has no benefit to the kid, just disadvantages.
That's why you let the kids run free. They go too fast, they fall over. Don't put them in something that gives them more mobility than they're capable of taking physical responsibility for. That's for when they're older and they can choose that themselves. And a good head trauma at that age gives the kid a very high probability of developing schizophrenia as an adult.
I mean, yeah, I remember really dumb things, like going out to the playground and playing on these solid metal swings (something like cast iron in the shape of various animals) with two chains on them. We'd wind up on them, then hold on while they unwound and flung us rapidly along. If we were thrown off, we'd be thrown off headfirst into an area populated by other solid iron swing objects, and the metal frame of the swing is well. Great fun, but clearly designed by a malicious mind, and kids below puberty really don't need to be risking their lives to have fun.
Anyway, it's not like this is a ban on guns or something; this is completely useless and only a danger to kids. It might surprise you that in most countries, you can't sell rat poison under a label that says "Children's Multivitamins".
