Well, my main concern was that a kid trips and falls with one arm under a wheel. Or gets shoved and moves a foot under a wheel. Or, well yeah, that the drivers just don’t see when a kid might have fallen in front of their bonnet.

You can’t control that. Sure, you can try to go slow and watch the surroundings of your car, but ultimately, the only actually safe strategy is to stop your car until the kids have moved away.
Well, or to let your kids out before turning into that street, which is like thirty meters for them to walk.
