The most dangerous points in a normal freeway drive are merging and lane changes. To exit and park you do multiple lane changes off and on, merge, and have to navigate local traffic signals.
Compare to remaining in your lane, in smooth traffic, when you can see well ahead and know it remains smooth, while making a call and saying, "Just letting you know it looks like I'll get there around 8:20." "OK, drive safely." click (Any other variant of this conversation ends with, "I can't talk, I'm driving." click)
If I needed to make a longer call, of course I'd leave the road. But for this, I believe that just making it is safer.
