There are a lot of qualifiers in this sentence, and they all lead up to a scenario that is not necessarily the one being described in the message I responded to.Does feel to me like 90 is probably ridiculous in any city in any case! That being said, Chicago suburbs do have an interstate with up to 14 lanes going through them where the left lane is just cars doing 90+ sometimes. (I am sometimes not sure Illinois actually does have any state police, appearances in the Blues Brothers not withstanding).
I guess the question is - if the right lane has space and doesn't have a lot of people turning into it and you aren't passing people and you aren't planning on getting in the center turn lane and there are folks who want to go faster piling up behind you - why stay in the left lane in any 4-lane (2 each way) situation?
But even in this scenario, the shortest answer is: Because people who regularly speed are naughty words and I don't feel a need to accommodate their behavior.
