Now, the Google Maps app on the iPhone is well worth a doff of the cap to. I use it several times a day, plotting the fastest route to and from work depending on how grumpy the M3’s never-ending roadworks are feeling, or when navigating around an urban area on foot.

Google Maps usually works a treat, as it probably does for countless others, given it is a free app and half the world’s population seemingly has a smartphone or three. It has saved many, many hours of my life from sitting in traffic jams I could otherwise have been stuck in, and got me to where I need to go without a hitch.

All this makes you wonder what the point of the humble aftermarket sat-nav is nowadays. You know, those things you buy in Halfords for that one trip a year you think you’ll need it for, plug into the cigarette lighter and then try to stick to your windscreen every five minutes when that infuriating sucky thing doesn’t work.
