I did stop to take the pictures, I guess the pictures must be lacking sharpness for you to think that the car was moving!
The one taken on my Freelander, I was standing on top of it to get over the greenery to get some of the lake in the view! It was windy and the car was moving so I'm not surprised that there is evidence of movement in the picture! Some of the pictures were opportunist, I had to just pull up walk a few paces to avoid obstacles like trees in the foreground, others I was able to stop in a layby and walk for the best composition IMO without the need for wellingtons and waterproofs.
I must say that I'm not upset by what you said, I take it that I need to work on technique or aarrrgh learn post processing, this thing is haunting me more and more! And yes I know I cannot fix out of focus or movement afflicted photos with pp but the rest might have made an impact!
