Is it to prevent the toothed drive wheels from skipping?

The outer wheel turns more times than the inner as is
goes around the curve.

I've noticed that all the Duplo track that's come with these sets has a ribbed
texture on the rails, with the exception of the curved track – that's ribbed on
the outside rail, like everything else, but the inside rail is smooth.

This has been puzzling me.  Can anyone think of a reason why the inside rail of
a curve piece should be smooth rather than textured?

Thanks,¬

(...) The old Lego track (12V and 4.5V) was like this too. tim (19 years ago, 4-Jul-05, to lugnet.duplo, lugnet.trains, FTX)
