Carpooling in Halifax

[Haligonian88]

I know that car sharing has become very popular in Halifax, but I'm wondering why more people don't carpool. I know there are carpool lots in communities that are a bit further out, but with so many people travelling in the same direction all the time all over the city, what makes people getting into a car with a stranger, or allowing someone in their car so difficult. Is it safety, inconvenience, or payment of the ride? Carpooling used to be very popular but it doesn't seem too common anymore.

Just curious to hear the thoughts on the matter from this group. Would you carpool? Do you? Would it not help the traffic situation significantly if widely adopted?
