What's a good site to compare car insurance companies?

[Phokus]

Can anyone recommend a good site? I'm looking at insure.com but i don't want to go through their web form because they ask for some really sensitive info like my driver's ID before i can get a quote... anyone have any experience with them?

Sensitive information is necessary to get a accurate quote.

On top of that, I wouldn't call a drivers license number sensitive.
