going 75-80 on I-80 isn't speeding. that's the pace of traffic even in the slow lanes. people do slow to like 70-75 if there is a highway patrol car nearby but since speed limits aren't really enforced 80 is the de-facto limit. and since cars are no longer the greatest cause of death in the US, they gotta let it go to cull the herd a bit and get that death rate up.
