For starter you wouldnt be able to scroll 9 items at a time like shown above.
Whats a user-flow that is better in the Taurus than in the Tesla?
I'm glad you brought up the scrolling and the screen shot. I ask you to take a look at the letter that is showing on the right - that the Tesla thinks it is on the letter "N" - but that the music that shows are at the beginning of the letter "M."
Further, when you scroll and have a large library (I currently have over 11,000 tracks in the car), it is a crap shoot whether you'll even get close. I have never been able to successfully find a specific track this way. At least in my Taurus, I could select ranges, then narrow down the selection, and then finally much more easily scroll track-by-track. Sure, I couldn't see as many tracks on the screen at once, but all that offers ZERO advantage in this case.
Also, the randomizer in the Tesla has no memory. I like to let the tracks play on a randomizer. The Taurus would run an initial indexing when I put a USB stick in and remember all the tracks (I suspect it assigned a serial number to each one). Then, as it was playing, it kept that randomization such that even over the course of several months, it never repeated a track. I could monitor that as I could see that the current track playing was 3,129 of 7,902 (or whatever) and it just kept its place day-after-day, even when I switched to another source (radio for example), it came right back to where I left off. The Tesla? Well, every day is a whole new setup. You would think that as many tracks as I have, repeats would be non-existent, but I am continually shocked by how often it happens.
Don't get me wrong: I am certainly not raving about the system in the Taurus (though the Sony system was actually pretty decent). But when that 10+ year-old tech offers a far better UX than what Tesla offers now, it is a sad statement about Tesla.
