I have a very strong "move out of the way instinct". In fact, that instinct has gotten me in trouble with my partner at least two times I recall when I was apparently supposed to protect her. but hey, you can only fight instinct so much!
The fun of the trolley problem is that phrasing it differently gets different results. In fact, in the most recent survey of English speaking philosophers, about 63% said they would not pull the level in the original phrasing, but then 56% said they would push a man off a bridge to save 5 live, despite the very similar phrasing.
edited to add that I found the survey. This links to a PDF, so it may download on click:
