Yes, those roads are great also. Page Mill, a mere 2 miles from my house is a bit bumpy, so I tend to avoid it. Plus TONS of bicyclists.
84 is GREAT if you can get on it with no traffic. I went for a drive with new and old M5s and one car, a Cherokee, would simply not pull into a turn out. I thought our lead car was way too far off the guy. When we hit those straights by the beach it was a BMW train passing that car. We were flipped off by him, the biker on the other side and the farmer on the tractor next to the road.
As we approached that little town, I think I was doing about 95mph with an E39 M5 on my ass when my Valentine One went gonzo. I was on the brakes hard and grateful that the E39 has such good brakes.
The same group took another drive, which I missed, in the Wine Country and it was supposedly so speedy that some guys rounded tires off. They were on some near deserted roads. I still say you should take that kind of driving to the track but we all do it sometimes.
Check out the thread at the M5 board. Some pretty crazy driving.
