There seems to be an emerging trend where the steering wheel, the single most crucial Human-Machine Interface (HMI) which we are constantly in contact with, is losing its focus on usability. In my view, the steering wheel is the ultimate interface for driver interaction. Usability isn’t just important; it’s vital.
I have deep respect for Audi’s approach – they've successfully modernised their steering wheel controls without losing the inherent feel and usability. I hope they continue like that.
For the BMW, I am a little unsure but leaning positively; despite my attachment to their classic steering wheels, the new switches on the iX performed well during my drive tests. It seems they've found a balance between innovation and practicality.
However, the recent direction taken by Mercedes is, honestly, a disappointment. They've replaced what were some of the finest steering wheel switches with multitouch controls that simply don’t satisfy. Similarly, VW’s steering wheel in the ID series has consistently received poor feedback from users in tests I've conducted.
I've worked alongside world-class designers who share a passion for tactility and usability, always grounding their work in evidence and user feedback. It's perplexing to see such reputable companies stray from these principles. In the quest for sleekness and differentiation, critical aspects like button separation, physical feedback, and clear tactility have been sacrificed.
This isn’t just about aesthetics or resistance to change – it’s about the safety, confidence and satisfaction that come from a well-designed control interface. The tactile response of a button can make all the difference in keeping a driver’s attention on the road.
Kudos to Rivian for their in-house innovation of the halo roller haptic system, looks very promising.
