The Best of Times, by Penny Vincenzi

Another one that has been sitting around. I realized yesterday that I don't really care for any of the characters. Great premise: what happens to the people involved in a massive traffic pileup after the accident. Why were they where they were at that particular moment? But...just can't care about these folks, many of whom are unpleasant people.

Traffic : Why We Drive the Way We Do (and What It Says About Us), by Tom Vanderbilt

Eminently readable, full of fun research...and yet I didn't finish it. My brain is not in non-fiction mode right now.
