We live in the Bay Area and have driven along the coast from SF to South of Santa Cruz many times. There is only one section of Highway 1 that would be only a little challenging. From Pacifica to just after what used to be Devil's Slide. Maybe about 4 miles in all that is curvy, but is doable. Caltrans has built a tunnel that all but completely by-passes the treacherous Slide section of the 1. After that it is an absolutely gorgeous drive along the coast, mostly 55-60 mph and relatively straight. You do have to drive what is a surface street thru Santa Cruz, but stay in the left lane and you won't have any problems. From there to Monterey is all freeway, just don't go much past Carmel, that is what the other posts were warning you about. Take 101 its still a beautiful drive and much less scary. Enjoy the trip!
