driving great Italian car on motorway: Lot's of fun.

Surely there's no fun whatever to be had on the motorway without getting nicked.
I'd say the decision depends entirely on the road. If you can easily fit in a long-way-round drive on the way home, ta-da! I used to have a 45-50 min drive to work, but I could have fun on the first half by zig-zagging through a load of countryside at almost no time cost. The will to live would start slipping at the approach of the ring road.
You can read a nice book on the train. There never seems to be any time for that anymore.
