Hey. Palomar is my least favorite road. I'm to the point I will not ride there anymore. I had 2 people go down in front of me last time I was up there. All from guys thinking they "should" be faster than me because they're on faster bikes and pushing way too hard. I like to get some lean on and get spirited. But I know my limits. Most of the guys up there don't. 94 can be the same way depending on the time of day. If you head out early on a weekend you'll hit very little traffic and not a ton of bikes. And the ones you do see usually are the better, smarter riders (like me! lol) When you get out there at 11:00 or noon, that's when you get the big groups and squids out there riding beyond their abilities.
If you're going to Paly, try to avoid Weekends anywhere from 8:30 to noon. They call it PIR (Palomar International Raceway) for a reason. And it's not a good one. I've been there when there's 40 or 50 bikes parked at the bottom and another 40 at the top. Not worth it.
Ride safe.
