Shaping behaviour isn’t about being flawless
I absolutely agree, but I think there are different kinds of flaws. If it creates a mere 2% increase in safety, that's perhaps worthwhile. But if it's restricting people who shouldn't be restricted, that's a hard no from me. If it's something as simple as clicking a button that says "I'm not driving", I'm okay with that. But if it can't be avoided at all as a passenger, it's a complete non-starter. If it requires unpairing from the car, that's a bit of a grey zone, but I'd personally lean towards "no". Why can't a passenger be the one to control the music (which must be the main reason to be paired to the car)? Surely that's increasing safety compared to if the driver is trying to do it?
