Because it should be okay, and it's a societal failing that it currently isn't as safe as it should be. Cars are always safer for their occupants, but using them puts vulnerable road users at greater risk of serious injury or death. In my city I love to see more people on the road with their kids on e-bikes. It shouldn't be a moral failing on part of the parent to be doing that. OTOH, just this morning one of the A*Hole parents back her SUV out of a parking space in a day care parking lot while on the phone and holding the phone to her ear. When I motioned for her to get off her phone in the DAYCARE PARKING LOT she shrugged and sped off.
