Unfortunately, there's not a lot that can be done if the existing infrastructure below ground requires that the cover is where it is. Rebuilding what's underneath can be pretty expensive, and the origin of this bad design may be centuries ago. :(
(It's a problem for bike riders in the main, and people who don't ride bikes usually have no idea it is even a problem, so you may get bad design like that even today.)

I got chatting to a Dutch motorcyclist in the queue waiting for the Harwich ferry a few years ago. I asked him what he thought of UK roads expecting him to say the surfaces were shit, etc. But the only thing he mentioned were the manhole covers. It's not so much that they don't have them in the Netherlands or elsewhere, just he felt the UK ones were so much more random in their positioning and their design, whereas Dutch ones all tended to be similar and in a line, and not in really hazardous places.
As the other posts say, it would be possible to make the surfaces non-slip. Just not a priority for UK councils / Highways England - DGAF.
In Germany, near where my MiL lives at least, they tend to be round with a circle of tarmac in the middle, like this:
