Holistic people tracking
Most of the large-scale "innovation" starts with uniquely identifying each actor then providing means to track them, so that from that all sorts of goodness might spring. This, of course, causes a bit of distrust among would-be end users of that fancy new tech. Put a focus on decentralised anonymised infrastructure -- cars that can locate each other in the vicinity but not necessarily identify more than location, speed, direction, perhaps vehicle size and weight, and that still can do all that without needing a centralised infrastructure -- and you can do most of the intended safety and other goodness without causing a privacy nightmare down the road.
Of course, this sort of thing you'd never hear from eurocrats. It just isn't a consideration.
