For the people that don't like the feeling of the first person mode I want to state that it is possible to get this trophy by just idling in the first person view. So if you want it you can leave your PlayStation 4 on overnight on first person mode and after the required 15 hours the Trophy will unlock.
As mentioned by
https://www.truetrophies.com/StephenBrown81.htm note that any time spent playing both single player or GTA Online in first person view will count towards the 15hrs required for the Trophy.
Feel free to comment if something needs to be added to the solution.
Happy hunting!
