46 is actually much straighter than 152. It was on 46, actually, that I discovered the Chrysler 300 (rental company Limited trim with 3.5L V6, at least) governs out at 115mph.

The additional mileage will, however, cost you about a 30-minute increase in driving time (unless you, too, are curious what your car's top speed is ).

Having grown up in Paso and having driven 101 between there and southern Ventura County literally a hundred times, I'll agree with mlshanks that it's the most interesting route. On the other hand, a family member who lives in southern Ventura County and used to drive to Santa Cruz every couple of months would always choose the 5-152 route because it was the fastest--especially if you set your cruise control to 90mph like everybody else.
