Safety through reading and paperwork or e-flightbags is paramount in aviation. NOTAMS, Wx, flight notifications, Checklists, pilot operating handbooks, SOPs. to name a few.
I would say only one thing would have prevented this accident, that is one of the participants becoming aware of the other prior to the collision. When in busy traffic environments take time to listen for traffic for some time prior to entering the mix, don't rush anything, have a good look around before entering a runway, and then before rolling. Landing aircraft need to stick to a predictable and orderly pattern, so other traffic have time to sight and follow. All aircraft need to broadcast intentions and allow time for responses, that is, no point making an entering runway call when the call is made when you are already entering and on the runway, think of the broadcast as a warning, you need to allow time for a response. A bit like the indicator on a car, it''s too late to signal when you are already changing lanes or entering the corner, the crash is already inevitable.
Also resist the urge to plan your lunch/meetup, where's the fuel pump, how's the weather conversation on CTAF, use a discrete frequency or land and get out the flight bag/phone. Just tell everyone where you are, where you are going and anything unusual you might be doing that might create conflict.
