I can't drive 55

Lower speed limits just mean more speeding ticket revenue.   People will slow down themselves if it saves themselves some gas money.

Yup.  I am all for a free economy.  Them with the bucks spends 'em or saves 'em....the wise invest 'em.  Why would I want to tell you to slow down to my speed if I can't keep up?  Yuch!

     I see some are talking about lowering the speed limit again, in the name of gasoline conservation.  Perhaps, it won't be the dreaded 55 m.p.h., like in the 70's, but I keep reading a lot about 65 m.p.h. speed limits being bandied about.  Without starting some kind of flame war:

How would a lower highway speed limit effect railroad operations and business?

Could the same mindset used to mandate a lower highway speed limit be used to justify slower speeds on airplanes?  Trains? Barges?
