Anecdotally, I see them all the time in my neighborhood, and they seem much more attentive to pedestrians and stop signs than regular drivers. Drivers in this neighborhood act like they own the place even though there’s probably an equal number of pedestrians out at any given time.

I’ve also seen one of them fail to pull over when an emergency vehicle was behind it, so I buy that they are causing some problems.

I have 2 ergodox EZs, a homemade redox that uses Bluetooth, and a homemade dactyl manuform.

For ergonomics, I’d say these are my priorities:

1. Split
2. Ortholinear with staggered columns
3. Tented
4. Mechanical switches

The arrangement of keys on the ergodox got me to start typing correctly, and I think the split helped a lot with my posture.

I had some bad luck with my dactyl manuform, the tenting was too aggressive, and the thumb cluster was angled in such a way that it put lots of strain on my thumb. I’m currently looking at replacing that with a Ferris Sweep.

Bluetooth was a mistake, the latency was unbearable. It led to one half of the keyboard being consistently slower than the other half, so I’d constantly make mistakes. I used nice!nanos fwiw.
