Oh wow, you just blew my mind. I am in fact thinking about littering! I was a bit suspicious about me not realizing the true meaning sooner, but did not look into it further. This makes a lot more sense now, thank you for clearing this up. :)

It's a common mistake for non native English speakers. I thought the same for years but now know the difference.

Also, a driving licence and a driving loicence are the same thing. The latter is just in a British accent.
