California next state for Mandatory Health Insurance?

Recently Massachusetts created a bill that required all people to have health insurance in their state. Could California be next? It looks like Schwarzenegger just outlined his plan. I'm quite curious how mandatory health insurance has affected people in Mass. Did everyone actually get health insurance? How do people get in trouble for not having health insurance? If you get pulled over, do they arrest you if you can't prove you have health insurance & car insurance? What kind of fines must you pay if you don't have a health plan? I would be interested to hear from people in Mass, and what people think of this in California. Quite frankly, I agree with a writer at LA times, when he said Making health insurance mandatory, isn't reform.

I believe it's important to have health insurance, but if you don't have it, it's not really affecting others, so you don't really hurt other people. Are they really looking after our best interests? Maybe they should ban unhealthy foods instead? Rather than requiring people to have health insurance, maybe they should try to make it more affordable so people can have a choice to buy it or not. Most people would like to have a health plan, so making it more affordable to those that can not afford it, would be a better plan, I think. So who would like to have health insurance mandatory in California? According to a post at a california health insurance blog, Kaiser Permanente HMO likes the proposal, and what health insurance company wouldn't enjoy health insurance being mandatory?
