Oh, there is a big difference in a gun and a car... Cars kill way more people in Hawaii than guns.  Don't you wish that everyone who wanted to buy a car or get a drivers license had to pass a Safety Class, have a Background Check, Profecience Test, 2 week Waiting Period,  Insurance?   And if they had an "accident" or "killed someone", drove without insurance, drove Drunk, drove Recklessly...  they would be arrested and their car confiscated ???  
And if they were convicted of a crime while "driving" they would get an extra 10 or 20 years tacked on to their sentence?   Wouldn't that get a few cars and drivers off our streets?   Yes, I would like to see cars and drivers treated the same way we treat legal guns and legal gun owners in Hawaii.
