I don't know that they are for sure, and am not sure what your perspective actually is, but what difference does it make? The most stolen car for the fourth year in a row is the Honda Accord. 1994's to be precise. What do you think drives that (play on words intended)!?
Should they be controlled to use only domestic gasahol, have 3-cylinder engines, and a maximum speed of 55 MPH? Registered in a national database under a Federal licensing system!? Should they be banned outright and their otherwise law-abiding owners made criminals overnight!?! Should Honda be forced out of business altogether?!?!
In 1992, when there were 35,000 carjackings per year in the US, Congress made it illegal to use a weapon "through force or violence or intimidation." Carjackings went up to 49,000 per year after that... Concealed Carry Weapons licensing in almost every state has helped drive this number down, but I'd bet carjackings of Honda Accords will continue to be a bigger threat to more people annually than nutjobs with the most popular-selling AR. Aren't carjackings and pre-meditated murder, as well as suicide, already about as illegal as they can be?
If you are blaming a tool, an inanimate object, and believe career criminals won't have (even certain) magazines and guns after a ban, bounce that thought off of Al Capone, any one of tens of millions of illegal aliens, or your friends next time they're rolling a joint. And remember that the most notorious smugglers in our recent past was Hussein Obama's Justice Dept. walking "assault rifles" south-of-the-border to Mexican drug cartels in hope of undermining the 2nd Amendment here.
