For the first time last night, I left the car outside. When I returned to it at 2am, it was around -2*C.
Anyway, I noticed the midline on my car was very sluggish when switching to different displays. Very sluggish. The numbers were blurring into each other. It didn't happen when I was on 'mpg' which changed second by second.
Just wondering whether other people have been affected by the same thing. I presume because of the cold weather, it's just slowed everything down.
