I accidentally did that again yesterday, when we were rushing to get home to let in a child who had forgotten their keys!
I've yet to correct it but it has a lovely red flag telling me part of the journey looks like it was in a car. Strangely enough I have a whole load of QOMs, but the best bit is that on one section I got a personal third, so that means I've be eaten the car on that stretch twice
I'm going to edit it later once I'm at a proper computer.
I also managed a 2nd overall position on one segment which surprised me as I didn't think I was putting in any extra effort along that section. But the last time I had one of those it took ages to get the QOM when I was trying to get it.
