craigslist?

I have a query that isn't addressed by craigslist.org.
Say I call a guy who is driving from Buffalo to NJ tomorrow, and he sounds normal, and says that he will drop me off at a transit station that will get me to Penn Station and from there I can get to Long Island, what is the likelihood of said driver guy turning out to be an axe-wielding homocidal maniac, and of me turning up as inspiration for a future episode of CSI New York?
