Making an urgent phone call to your spouse while rushing to your kids in the ER without taking your hands off the steering while is a fucking godsend. No matter how broken they are currently, they do have their place, and they work at least a bare minimum.

You should just drive and call later. You are putting yourself, your kids and the people around you at risk by calling someone else while driving, even when keeping your hands no the steering wheel.

I'm not a parent, but I suspect that if you're driving your kid(s) to the ER, there's a risk of having hours or minutes left with your kid(s) before they perish. So while it is riskier to call on the way, the risk of your spouse missing out on the last few moments of your child's time on Earth is actually greater.

That being said, one would hope that is a seriously unusual edge case for requiring voice commands.

(I personally find it awkward to use them, and still don't trust them to get it right, so I try not to use it ever unless I have no other choice.)
