Is it time to ban cars?

I'm shocked and saddened to read about last night's terrorist attack in London where cowards used a car to mow down innocent pedestrians before continuing their rampage with knives.  Similar car attacks happened in Times Square last month and in Paris a year ago.  

As we've seen over and over again, a gun isn't the only tool used to commit mass murder, yet no one is talking about banning cars or tractors.  Mass murders cannot be stopped by outlawing guns.    

It has been proven over and over again that guns save lives.  Reducing private gun ownership or restricting the ability of law abiding citizens to carry guns will only serve to make us all more vulnerable to madmen who seek to cause mass casualties.
