I took this hwy 1 scenic road from san jose to down south only once ever.... and never again.
Why? cot dayam 10 hours vs 6 hours straight highway driving. All them curves messes up your automatic transmission. My dad's car trannie was shot once we were in santa ana. Good thing for viet mechanics down there to fix it and we had our car back after the weekend was over.
Horrible experience and never again. Well not going all the way but maybe using that highway to get to places like Pismo beach but with a rental though. Mess up them rental like we don't care.
