I had a buddy in high school that drove an older F150 with a "three on the tree" shifter. Gebus that was ridiculous. I never got it. It was just stupid.
The first time I got into a brand new BMW 7 series with the iDrive system, it took me about ten minutes to figure out just backing up of the parking space. It took looking at the owners manual to finally get there. I don't remember exactly what the procedure was, but it was ludicrously complicated (selecting reverse and disengaging the parking brake) and there were no visual cues to guide you. There also wasn't an actual hardware device of ANY kind for the e-brake. No handle, no pedal... nothing. Whoever came up with that shit needs a kick in the taint.
Paddle shifter cars (especially early examples are just as bad. Trying to park some of them is nearly impossible.
I'm a known FIAT fanboi, but this too is just a bad idea, or at least a failed execution of a potentially good idea. It may work great, but if it confounds the driver in any way, it isn't a benefit at all. People don't like "change" when it comes to a lot of things. Even when it's a change for the better, there will be resistance. Lesson to car makers here should be a reminder of that fact and a call to make the adjustment from old to new as painless and easy to understand as possible. Just throwing it out there is a bad practice.
This comes down to a combination of many factors... yeah, people are morons, yeah, it's a shitty design, yeah, we are slow to embrace change. Pretty much a perfect storm of stupid.
