Maybe I am missing something but one is taught to do turns during the PPL.
It has been dumbed down now in line with everything else. You get an initial "straight line" rating allowing you to fly in a straight line from a to b, after which (100 hrs P1?) you can take the test for "turns rating". This new rating allows you to fly from a to b but not in a straight line
Actually I am being facetious as you can probably tell. It does make you wonder though - The FAA PPL includes various "ground reference" manoeuvres, which require coordination and flight often at low altitude, and a newly qualified PPL should in theory be able to do these without stalling, spinning, crashing, etc...(any of the previous leads to an instant withdrawal of the certificate
).....
