Narrative Ending

For the ending of my narrative I have came up with a two slightly different ideas however as of now I'm unsure with what one to go with.

1. It ends as the protagonist with a decision whether to risk his life to save someone from a car crash, then it cuts to black before he makes a decision and you hear the noise of a car breaking and someone being hit, leaving the audience to decide who got hit by the car.
2. the protagonist remembers the location where the crash happened and waits to try and save who he saw in his dream. After a while no one turns up so he thinks that his premonition was fake and wakes home and as he crosses the road he gets hit and it turns out the person he saw get hit was himself.

To decide I could create an questionnaire to ask people which they think is best

Update
Ive decided to with 1 as i feel this will be easier to film as I wouldn't actually have to film someone getting hit by a car also it would create more enigmas as the audience wouldn't know who gets hit.
