What owners wrote
Vehicle 1 operating normally in traffic on [XXX] in Westfield MA. Operator 1 notices alert on dashboard. As Operator 1 looks down briefly and returns eyes immediately to the road, she sees Vehicle 2 braking to slow or stop. Operator 1 depresses brakes, but vehicle does not slow as it usually does, nor does Automatic Emergency Braking engage as it always has in the past. Front of Vehicle 1 makes contact with rear of Vehicle 2.
