I’ve spent some time in a Juniper Model Y and BYD Sealion 7.
The most notable areas where BYDs are still not competitive with Tesla are the interior (fit and finish is worse, the styling is unrefined and busy), the software (a buggy lightly skinned version of android), the suspension (BYD feels floaty whereas the Model Y feels grounded and responsive), and parts availability. If something goes wrong with BYDs in Australia, you can be without a car for months while waiting for parts to slowly steam across the ocean.
The BYD is cheaper, but only by about 10%, which is not enough in my view to offset the overall feeling of still being a work in progress.
That said, I really hate the onscreen gear selector in the Model Y. I’m fine with most controls being onscreen but I want a physical control for gear slection.
Some of Tesla vehicles are as innovative as ridiculous and illegal(in many countries).
