Has Kwinana Freeway traffic gotten worse or has it always been like this?

I only recently started using Kwinana Freeway and was always under the impression that outside of peak traffic times it flows well.

I’ve driven into the CBD at 10am on a weekday sometimes and it’s always been congested af.

I’ve driven South at 2pm and it’s also a mess at this time.

Has it always been like this?
