As the creepy zombie girl on the telly says: "if you hit me at XX speed, there's an XX % chance I'll live"
If you don't wanna be a child-killer, just drive slowly (especially when near a junction, for example). Easy. Now the worst you'll do is some bumps and scrapes, so it doesn't matter how stupid they are, you're spared the horror of seeing them explode into teenaged offal all over your windscreen.
