Its harder and takes much longer to get your car registered than to buy a gun.

Totally depends where you live. New York has some of the most comprehensive gun legislation in the world. It's essentially impossible to get a permit for concealed carry.

However, it's quite trivial to obtain a gun illegally, as one can see from the crime statistics. Even though your complaint about the lack of gun control is true in some states, it's obvious that even the most stringent gun regulations would have little to no effect on the availability of illegal firearms, which are disproportionately responsible for gun violence.
