Focusing on laptimes can have expensive or even tragic consequences

My advice here can be summarised in one word: don't. I say this for three reasons ...

First, and most importantly, it puts pressure on people to push harder than may be wise, especially if they have a 'goal' in mind. In particular, when you face a situation where you have to decide between sitting behind someone for a bend or two and pushing past them, thoughts of seconds ticking away are bound to play some part in that decision.

In the worst-case, you may kill someone by trying to shave off a few seconds. Both marshalls and police report that a disproportionate number of serious crashes have a running stop-watch on the dash or handlebars.

Second, it's pointless and meaningless. There are no trophies for tourist laps, and the variations in traffic will always be greater than any variations in your driving performance.

Third, if you do have a serious crash while timing a lap, the police report will include details of any stop-watches, dash-timers, etc, they find. Your insurer will then invoke the 'time-trial' exclusion that is standard in every road policy, and you will find yourself personally liable for the GT3 you hit or the biker you injured.

Tourist days are about having fun, not setting lap records. There are many other ways to judge your progress at the track. If you want to go for laptimes, you don't have to pretend to be a race driver in a Touristfahren session, you can be a real one in one of the race series' available.

This is also the reason I have no laptimes on my site: I don't think they belong on a site geared to tourist driving.
