I go from sac to la all the time. After stockton its almost like the autobahn if there aren't tons of trucks causing gridlock. However there are many white camaro cruisers that frequent I-5. I usually just floor it in the open in between overpasses and then bring it down to 85 when passing rest stops or the exits for gas. I wouldn't be so cocky to simply set the cruise at 100mph and think I can make it the whole way, that would be a gamble.
