SatNav and NavSat

We went from Hull to Harrogate on Sunday. And then, because we wanted to get home, we went from Harrogate to Hull. On the way back the sat. nav. tried to send us a different way from the one it used for the outbound journey.

I hate this. It happens most of the times that I go somewhere and then, surprise, surprise, come home again. It reminds me of one of my favourite railway station jokes:

Customer: "I'd like to buy a return ticket please."
Ticket seller: "Where to?"
Customer: "Back here of course...."

Anyhoo, for any navigation software writers out there, here are a couple of tips for your next version. 

  1. If I try to plot a route that seems to be the direct reverse of the one I've just driven, just reverse the route and give it straight back to me. 
  2. If you're planning a route from A to B, plan it from B to A as well and compare them. Then pick the best one.
