They don't have to be marked constant radius. Non-constant radius
curves on ramps and highways are not frequently encountered and should
be noted through yellow diamond signage.

So you're saying that I should ignore what's ahead of me in the curve as
well as not pay attention to traffic on the road I'm planning to merge
on and just look at my speedometer then? My experience tells me
otherwise. I've also read that braking while in a curve is a good way
to lose control one's vehicle. IOW, one should slow down before
actually getting into the curve.

When I'm paying attention to the road, I adjust my speed as appropriate
without the assistance of the speedometer (which I really only look at
when my RD goes off).
