Teslas have their charge port on the rear 3/4 panel on the driver side. The Taycan's location of the DC fast charging port on the front passenger side also means it will be compatible with Tesla Superchargers when they open up to other brands over here, much because CCS. If you want to use a Tesla Supercharger you just have to park in the opposite direction of what you would with a Tesla, where you reverse a Tesla in, you can just park nose inn with the Taycan.
The Audi E-tron has the charge port right in front of the drivers door, which will be messy, as you easily end up occupying two spots. Basically, public charging locations tend to look very messy as cars have charge ports in all sorts of weird locations, meaning people will park all over the place. Additionally, some high power chargers have water cooled charge cables, which means they vibrate when you charge, so it's not a good idea to let that rub against the side of your car, so you have to keep in mind that too.
