This is one of those things my dad taught me that stuck with me! The UK's highway code has a specific rule about this on normal roads: "Do not reverse from a side road into a main road. When using a driveway, reverse in and drive out if you can." Backing out is so much more stressful and more dangerous – I get to experience both as my spouse is a 'drive in' so if I ever take their car, I have to reverse out ;-)
It did make me chuckle that the person defending the 'driving straight in' approach in the article is wearing a face mask incorrectly, but my spouse shares their 'easier to load stuff into the trunk' argument which I concede has some merit..
