@kezo I think that our usage is very different. As I understand it, you are doing a school run most weekdays that is within the EV range. By contrast, I only have one journey a week that is entirely within the EV range and, in fact, in the winter the reduced EV range leaves me about 5 miles short. Almost all my other journeys are beyond the EV range although, thankfully, they aren’t that frequent (one or two a week).
Also, whilst I don’t drive with a heavy right foot these days, I do a lot of motorway miles and usually have cruise control on at between 70 and 79 mph. My sense is that this sort of speed doesn’t help the fuel economy, but I’m not going to pootle along at 56 mph just to save a few quid or worry about range.
I think our problem is that up until last year I was taking my wife out 2 or 3 days a week, and those journeys would all have been within the EV range. Her condition has deteriorated since then and she now only really wants to go out once or twice (max) a week, hence why the shorter journeys have become a lesser proportion of the cars usage.
