02 — The drive
A hundred and twenty miles, and two places it can go wrong.
The line is the 405 south to the 5, then the 5 the whole way down: Long Beach, Irvine, San Clemente, Camp Pendleton, Oceanside, Carlsbad, Del Mar. Once you are past San Juan Capistrano it is genuinely one of the better drives in the state and it holds a steady speed almost all the way to La Jolla.
The two constraints are both at the Los Angeles end. The first is the southbound 405 between the 105 and the 605, which in the late afternoon adds forty minutes on its own. The second is the merge at El Toro where the 405 meets the 5, which loads from about three o'clock. Get past both and the remaining eighty miles are predictable.
On an afternoon arrival the chauffeur will often take the 105 east to the 605 and come down that way instead, which reads longer and finishes sooner. If you have a fixed appointment at the other end, tell us and we will build the whole thing backwards from it.
