Unsafe at any speed
Posted: March 7th, 2007 | Author: Andy | Filed under: Archive, Design & UX, Systematic Viewpoints | No Comments »Two weeks ago I picked up Audi’s new Q7 SUV. It’s my third Audi, having had an A6 sedan for the last few years and the A6 Avant (wagon) prior to that, along with various euro-SUVs. I love Audis and the Q7 seems to be a great vehicle on all counts except for one glaring problem. German automakers like Audi, Mercedes-Benz and BMW have adopted a master controller for many functions in the car. Audi has MMI, BMW has iDrive and Mercedes calls it COMAND. The thinking is to provide access to controls and settings while reducing the ‘confusing’ array of dashboard controls.
Changing a radio station or CD track requires multiple steps. At worst the driver needs to select a function via one of eight buttons surrounding a knob, turn the knob to select a menu item and press the knob to select the function. If you are already in that function, you eliminate the intial button push but still have the turn and click. I have to take my eyes off the road frequently to check my selections. No matter how close to my line of sight the display is I’m no longer aware of what’s happening around me.
I acknowledge that these systems are known to require either long or steep learning curves. I want to give it a chance, but I hate it. Controls for vehicles need to be direct and avoid visual diversion beyond feedback for aiming at a control. I acknowledge that these systems are known to require either long or steep learning curves. I want to give it a chance, but I hate it. A system that complicates simple actions and requires learning to perform the same functions I perform simply and directly in my other vehicles is flawed and is exposing me to risk. My wife is completely intimidated by it.
