What happens if you don't get car insurance?

I wrote a similar question and got jack-*** answers, if you feel the need to do that, don't answer at all.

Whats happens if I don't get car insurance?
I have a speeding ticket on my license, I'm about to go to court for another speeding ticket (19 over) and a reckless driving ticket (for burning tires). I am 18, with a Nissan 300zx (2 seater sports car)

I was thinking, what if I don't renew my insurance? Will I just get a $200 ticket when I get pulled over for it? $200 ticket >>> $300 a month for insurance

I personally think the insurance system is very faulty since insurance companies are making lots of money. If it was a service where the profits went to roads and such, I wouldn't mind a bit.

What is the penalty for not having insurance, costs/tickets/fines?

No smartass comments please, just asking a question, I highly doubt I will drop insurance, as I pay it every 6 months anyways. Just wondering
