A question for the snowbirds

You need to help your fellow folks out there! I live off I8, their main migrant path, and the amount of people who hang in the fast lane doing 65 is astounding. Thought maybe there was something wrong with the right hand lanes in Arizona and that’s why they never use, but my cousin in Phoenix was unaware of any issue:p
Haha, it must be a Tucson thing, because they do that ALL the time here. Just camp out in the passing lane. Drives me batty.
