I read this and then read one second after, and found the latter one more realistic.

I read both as well. I enjoyed 'Lights Out' better but they're both great reads. 'One Second After' had the advantage that the author has connections inside the government. I believe the foreword was written by Newt Gingrich.

From researching EMP on the net, it seems that more vehicles would survive as is the case in 'Lights Out'. However, maybe the government knows something we don't... ;)
