Same thing happened to me as I was driving home from the dealer after I had purchased the car. It was an 1,800 mile trip home-which explains the coke and I was part way home. As I was going through a town at the time, I had just gassed up and was saving the soda for the freeway when a left-hander unleashed a furry of fizz. Fortunately it was only a pinhole but still I head this thing hissing and looked down and as it rolled, it was shooting all over.
I feel your pain about the soda, sorry bout the rain though, that has gotta suck.
