Yea, like you can drive 85 on the Balboa Peninsula or PCH.
People here in So Cal still drive at the speed limit once in a while. Around my town I get passed going 65 but at 75 I may be fastest car on the freeway. No one drives 90 unless they're racing sooped up Civics and other small cars on the freeway. And the cops call that reckless driving. That ticket will get you a free "Go To Jail" card, an impounded car and lots of points on your driving record.
California has some of the worst roads in the country. I wouldn't thrash my vehicle driving fast on them. The speed limits in Nevada and Utah are higher. The freeway to Lost Wages is a straight boring desert run and yea, people drive to Vegas at 90 mph. If you're really driving 85 to 90 on So Cal highways think about slowing down.
