I sincerely doubt the UIs are getting worse year after year. If that were the case, we would have unusable devices by now.
Anton Yelchin, who played Chekov in the new Star Trek movies, was killed Sunday when his own vehicle rolled backwards.
It has recently emerged that his vehicle was a Jeep. As discussed on Slashdot previously consumers are having a hard time knowing if the vehicle is in "Park."
The new gearshift design for the Jeep Grand Cherokee appears to be causing rollaway accidents: 121 crashes and 30 injuries so far. The gear shifter is designed to look and feel similar to a traditional automatic gear shift lever but it is meant to cycle through the gears rather than move directly to a certain gear. A driver who is used to placing their vehicle in park by pressing the shifter all the way forward may instead be setting it to neutral before exiting the vehicle. The NHTSA is investigating.
I'm going to call this an unusable device.
