There is a long stretch of roadworks between home and work at the moment and the speed limit has been dropped to 30km/h. This limit is for both the protection of the workers and of travellers for there is a lot of heavy machinery on the site and it crosses the road frequently.

I have to admit that I get a perverse pleasure in ensuring that cars behind me are travelling at 30km/h as I have noted that very, very few people actually obey this limit. I'm quite happy to be leading a line of 15 or more cars through a couple of kilometres at 30km/h.

In fact, woe betide you if you come speeding up behind me when I am half way through the roadworks as if I am in a cheerful mood, and I often am when driving, I'll happily travel at 15km/h to ensure that you haven't saved any time.
