Honestly I'd be fine with blinkers being anything, make them emojis for all I care, _except_ arrows pointing the wrong direction. The quirkiness isn't the problem at all here
Same. I drove a MINI for 18 years partly because they are so quirky and that's enjoyable, but this is simply the wrong kind of thing to indulge quirkiness in.
Turn signals need to function well as turn signals. That's vitally important. You can't fuck with that by making the signal actively and hilariously misleading. It's just not ok.
Ah, yes. Form over function, the driving principle for many insane UX "improvements" over the past 20 years. Personality is great. It's not more important than clarity or other related concerns though.
I doubt anyone would’ve called it stupid when the arrows pointed in the direction the car would be driving. There’s zero common sense in reversing them.
