My attitude (personal so not trying to lecture others) is that driving a car involves a degree of risk, how much risk varies impacted by many factors. Massive issue is that this risk is not just risk to driver but risk to others that have no choice about or control over decisions the driver is taking.
Professional drivers, people who have been driving over many years, etc. have accumulated a lot of experience about risk and subconsciously often recognise small signs that focus their attention reducing risk. Younger less experienced drivers are still accumulating that experience. Insurance premiums highlight this difference.
Add that younger people can be more focused on their phones, sometimes placing more importance on latest Tweet for somebody they follow.
Whilst OP does not ask about this aspect, has in all probability considered it, discussed it when daughter was learning to drive, etc, there are suggestions in the question that the daughter may be a younger less experienced driver. When driving with a phone, all legal/sensible things on that phone can be achieved without prominent add-on screens ie without the added distraction eg using voice control, then I personally consider raising questions about the need and distraction risk useful, maybe if only as other many non-forum members might also be wondering and reading the thread (it's a forum open to everybody on the internet to read)
