True, H.B. ain't no Portland Oregon. The roads may be wide enough for cycling but not that friendly. Its not just the road widths but its the mentality of drivers. I don't see much difference.
The scenery along Pacific Coast Highway in Huntington Beach, Seal Beach, Newport Beach, Laguna Beach, all the way down to Dana Point is really nice. Most of it is wide enough, except for parts of Corona Del Mar, Laguna Beach.
