TBF if I was in an assisted vehicle driving towards a stationary vehicle (as big as a fire truck too!) I would probably expect the systems to slow the vehicle before any collision. Wonder what happened in this instance.
If the driver is supposed to maintain a grip on the wheel this hardly sounds like an autonomous vehicle the way I am imagining it. Maybe there should be a tiered system to inform users exactly what level of engagement they are expected every journey before the vehicle moves?
