Traffic cops!

Your driving down a busy road and you come upon a cop that has pulled over someone for something. And where is the cop car? Taking up atleast 1 lane, maybe two! What's up with that! They got radios! They got pa speakers! Is it too much to ask that they use them and tell the driver to pull up to the nearest parking lot? There's no increased risk to the cop and the road might be a little safer!

Come on guy's, think it through!
