There are 254.4MM registered cars in the US according to a 2007 DOT study. The US Census estimates there are ~310MM people in the US as of 7/2010. I'm not sure how many are citizens - perhaps ~300MM for a round number. That means ~0.85 registered vehicles for every man, woman and child in the US (or 85 vehicles per 100 people)
Yes, there are many US citizens who have cars, but there are many US citizens (like those who are children, those who can't afford cars, etc.) who do not have cars. There are over 250 million registered motor vehicles in the US.
150,000,001
16.1 million
In 2013, there were 254.4 million registered cars in the United States. That does not take into account all the cars that are unregistered or wrecked.
Gun owners aren't "registered" like cars. One estimate is that there are @ 4 million or so gun owners.
