have u guys started slowing down or is it just me and a few coworkers.
Yes, but it's to avoid getting nasty tickets ever since they increased patrols on I56 rather than saving fuel.
You're car's aerodynamics/weight has a lot more to do with it, which you really can't change. Also, you burn a lot of fuel from harsh accelerations, redlining, driving WOT frequently, which people don't really do (well at least most people don't do).
Personally, I'm trying to keep things lately on I56 to avoid the dreaded +20mph speeding tickets that don't usually allow traffic school, though interestingly in SD, they still let you go to traffic school if on the freeway you end up get clocked above 85 but below 100. Guess we need the revenue.
