Why sometimes my car slows down going downhill?

Mothra@mander.xyz to No Stupid Questions@lemmy.world – 33 points –

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?

Generally much less effectiveness to almost none as they get hotter

Can you continue using them once they cool back down, or does the heating cause permanent damage?

At some point it probably does. And can probably catch fire. Mine were fine once they cooled

Thanks for the reply.

I was wondering if safety was like motorcycle helmets - I read that if you dropped them, like say, you kept them on the seat of your motorcycle and it fell off onto the ground, it's no longer safe for use and needs to be replaced.
