Some may also argue that possibly inciting road rage because you somehow feel it is your responsibility to slow people down by doing something illegal yourself is also reckless. This is of course assuming your left lane laws are similar in the great white north so I may be incorrect. Here in Washington the law states nothing about the speed limit in the section about clogging the left lane, only to stay out of it unless passing. They even run enforcement campaigns occasionally, but those are rare unfortunately.
