Did anyone actually slow down to 55 MPH in 1974?

It was so bad, you'd see packs of cars on the highway, all doing 54, with a cop in the lead.

You still see that here. Matter of fact, if everyone around you is going 65, there is a great chance there is a cop in there with you. God Bless Texas, 85 MPH speed limit. And they usually are going 10 faster than that.....
