b) To engage the brake, you have to push the lever, and then it moves back to its original location, like a joystick. This means that there's no positive tactile feedback that the brake is engaged
To quote:
"The problem is that the "Monostable" design doesn’t provide any meaningful feedback about what gear you’re in — it returns to the center position after each shift. To completely confirm if you’re in drive or park or reverse, you have to look at either the LEDs on the shifter (often covered by your palm) or the digital display in the instrument cluster. This has confused thousands of people, led to over a hundred injuries, and now potentially a death. And it’s all because of a design that prioritizes screens over switches."
The 2014-2015 Grand Cherokee was recalled because of 304 vehicle rollaway incidents, 117 crashes, and a death.
There is no excuse for this kind of "too clever" design.
People drive while tired. People drive in emergency situations. People drive while distracted by screaming infants.
You can't blame dangerously bad user interface design on the users. Essential safety settings should be designed so that the operator falls into the pit of success instead of stumbling into the pit of deadly failure.
