How to read whilst you drive

Having resigned from my current job, I'm planning ahead to the 'new' job, and how to handle some of the changes that are coming up.
The new job means I'll no longer work from home most of the time, and will likely be covering a lot of miles.  30,000/year sort of miles...
The only benefit that a train has over a car (that you drive, as opposed to being driven by a chauffeur) is that the time spent travelling needn't be dead time.  The choices are many; do some stuff on the laptop, play on the Nintendo DS, read books.
Whilst musing over the loss of two useful hours each day (driving/commuting) Andre suggested that I could still 'do' books, by listening to audio books.  But of course!  Why didn't I think of that?
Having an Amazon 'Prime' account, along with a motivation ('reason') to buy (audio)books is rather a dangerous situation for me... so many titles, so quick and easy to order, so fast for delivery...

I must step away from the computer now before I do something both my bank balance and I might regret ;)
