Well, I suppose everyone but me had this bit figured, but well impressed again.
I'm at the eastern end of the M8, heading for Glasgow, this time to the car park I normally use so I am in no need of a satnav. However, the traffic was atrocious, and I started to worry if I would get there in time. I remembered that although I had no idea of the traffic ahead, AA would know. I pulled over for a couple of minutes, got my phone connected, AA up on the screen, and entered my destination.
AA immediately informed me I would get there by 18.47, which was OK but not exactly excessive for my purposes - curtain-up at the theatre was 19.15. I wanted to buy a sandwich and a drink, and consume these, before going in.
I kept AA onscreen, of course, and as I approached Livingston I saw an alternative route indicated as "six minutes less". Hmm, I could use six minutes, I thought. So I turned off the motorway and followed the directions into Livingston, going round a cloverleaf interchange I have met before and would normally avoid like the plague. I mean, that place is a mess of roundabouts, and just this week I discovered my ophthalmologist has moved his clinic out of there partly because "Livingston is not a place you want to bring people to if they have an eyesight problem."
I just followed the blue line, along roads I would have had no clue about under normal circumstances, and still the arrival time was showing as 18.41. Eventually AA guided me back on to the motorway, which was still fairly gummed up, but I had clearly skipped a very bad section and gained six minutes. Which made all the difference, as it happened. Sandwich and drink duly queued-for and bought and consumed in time for the curtain-up. Good show.
