other than the obvious dripping while driving or running out of battery power or e-liquid...
The other day one of my cartos was overfilled and making that gurgling noise, so I went to blow it out into a paper towel. I must have used to much breath force, however, as some of the liquid bounced back into my eyes. Man, e-liquid is gross when it gets in your mouth, but in your eyes it burns and is an all-around unpleasant experience.

Thank goodness I was at home and could run to the bathroom sink for help. In my car or at the cafe it would have been a bit of an issue. OTHER THAN THAT, vaping has been very enjoyable for me.
Just a word to the wise: don't blow too hard.
