Why are you running the 5 so much? You just want a lot of distance? If you'd prefer more enjoyment and less miles/hour you should run the 1 and 101 up and down the coast instead of the 5. The 5 has some LOOONG stretches of freeway with nothing.
+1, the 5 will be a bore, the 1 and even the 101 offer much more.
