I realigned the streets west of Date in Montara to match the Yahoo aerial photos. I walk these street all the time and am intimately familiar with them. The first few blocks west of Main were OK, but then, everything went kind of wonky on the TIGER data.

Still to do:

The streets west of Main are not correct, as they are shown crossing Hwy 1.

The streets east of Date, the back end of Montara, are a mess. There's no grid back there and the traces seem to be going every which way. Also there are some non-existent streets show, where there may be county paper streets (e.g. Montara Blvd). This will require more work, and almost certainly GPS traces to get them right, as well a the use of a Walking Papers map for note-taking.
