Had a bit of annoying charging logic in the car navigation yesterday. Travelling south down the M1 I wanted to charge at the new Luton SC (which is great by the way), which is our exit anyway. I added the SC as a stop and the car said I’d arrive with 8/9% remaining.
But that seemed to be just on the threshold where the car wanted to redirect me to another charger en route (Newport Pagnall). The first annoyance is if you don’t immediately notice the reroute (and of course there is no audible notification) and press “remove charging stops”, you have to replan the original trip and hope it doesn’t feel the need to reroute you again. Eventually I just left it routing to Newport Pagnall with the intention of ignoring it. I had hoped as soon as I went past NP it would revert to Luton, but no - the logic preferred a round trip up and down the motorway back to NP as opposed to continuing to Luton, even though the distances were comparable and ultimately there was comfortably enough battery to get to Luton.
I had hoped/assumed the navigation would be more sophisticated than this.
