I drive a small automatic car. For the most part, it struggles a bit with steep uphills, and picks up speed when going downhill. That’s to be expected.
But then I noticed some downhills actually slow it down. I’ve noticed during a two-hour motorway trip I often do to visit family, there are some specific downhills, not all, just some, where my car always slows down and I have no idea why.
Ideas?
Well, it’s a 110km limit zone for the most part, I’m usually sitting somewhat under the limit but typically above 100. I don’t know how steep these slopes are. Maybe I’m under/overestimating them as a consequence of driving, slopes become obvious on foot. They don’t appear to be particularly steeper that others where my car doesn’t do this. They are certainly not very steep though, because there are a few of those and I gain and lose a lot of momentum on them.
