You can't parallel park, & you still have a Licence?
It was mandatory, when I did my Test years' ago.
Like another commenter above, driving instructor told me about rear spot, & when needed, it works perfectly!
These days, there's really no requirement to do it, as all bays at S/C's are nose or tail in.
I'm spot on with reverse parking, even though my dear Ol' Datsun Skyline is manual, very long, & no power steering!
