FWIW I was living near Arcadia/Covina and commuting to Santa Monica. What area of LA did you live and work in to have such a nice commute?
Your commute was definitely a tough one! A big issue I've noticed is that a lot of people work in west LA, but the housing prices are so high that most can't afford to live there. This also leads to much higher traffic for commuting in that direction.
I certainly hope LA has strong, long term plans to improve the commuting/traffic situation for the area.
At the end of the day I gave up on the job that required that commute--it was very stressful and not worth my health. It makes me wonder how many other people are effectively locked out of job markets in LA because they don't have cost and time effective ways of commuting there.
Certain parts of the city are easier without a car than others. A lot of it comes down to how far you live from work too. I walk to work everyday (10 minutes) and there's a plethora of stores in my area to walk to and shop at.
I'm about to sell my car and I'm not sure if I'll be getting another anytime soon.
