With hundreds of thousands miles behind me, happily accident-free, I reckon I generally know when I am driving at a safe speed for the conditions and, given fair reminders of the speed limit (often lacking) would rarely transgress by more than 3-5mph. To get more feedback on my speeds I decided some months back to install an extra (digital) speedo which sits before me on top of the dashboard where any front passenger can also spot and tell me when I commit any breaches and help keep the so-called 'safety-camera-partnerships' out of my pocket. Despite all this it is ludicrously difficult (indeed impossible as these highway-robbers well know) not to stray by the odd small margin unless one glues ones eyes to instruments instead of to the road and, like most motorists, I will no longer be surprised when the morning mail eventually lowers my spirits with a fine and points on my licence. As in so many other aspects of UK life commonsense has been turned upside-down in the past decade. Witness, for example, the masses of OTT road-markings that can be afforded but not, it seems, suitably-obvious speed and speed-limit reminders which would be a sight more conducive to road-safety than any number of speed-vans and cameras craftily clicking up the revenue for their quangos.
