Just got back and loved it. I found some good advice on the net before I went and thought it was worth sharing. If you drive North to South you are on the right hand side closest to the coast for better views. More importantly, there are many opportunities to pull over and enjoy the spectacular views. It is much easier to just pull over to the right rather than make a left turn in traffic. The driving is hard enough without adding that as well.
I went in September and it was busy enough so it must be really busy in the height of the tourist season. Weather was coolish but sunny for my trip but a hoody or jacket was enough.
One last thing you might not think about when planning the trip. During my trip, the mist or fog was there in the morning obscuring some of the views. Later in the day the fog burns off in the heat and visibility is good. So it was my experience at least that the early bird might not catch the worm :)
