I don't know much about what's going on in Southern California with the shutdown of the 405 freeway. However, you know your public transportation system is flawed when you need to take an airplane to travel a distance of roughly 40 miles. This is almost the same distance separating the airports in San Francisco and San Jose.
I suppose this is another reason I'm lucky to live in the Bay Area. Between buses, BART, and Caltrain, I have many ways to get around if my car is ever unavailable. Bay Area public transportation is great, and location relative to public transport has played a key factor in my apartment search. My eventual plan is to rely primary on buses and BART to get to work, and use discounted commuter checks provided by my job to save money on fares.
Good luck to everyone that will be affected by the 405 shutdown! I will admit that $4 (with $1 extra for first class) is a great deal to ride JetBlue . Definitely something I would have considered if I lived down there.
