2. Having no regard for accepted rules or standards.

This is the province where drivers are likely to
(a) back up on a major street
(b) stop randomly to let a car in which is having trouble getting off a side street onto the main road
(c) stop randomly if a pedestrian even looks like they're thinking about crossing the street (causing great screeching of tires behind them)
(d) wave other cars through continuously at a four-way stop sign, without regard to right-of-way; or, alternatively, not stop at all, viewing the stop sign as merely a suggestion

So, I think definition (2) applies.

Regarding licentious: They say if you go up to Signal Hill at night (where some licentiouness apparently takes place), the city lights spell out "SEX". I haven't checked this one out personally.
