It won't be cyclists that encounter this problem. I would predict that there will be more deaths on the road for pedestrians. Every day I experience pedestrians stepping out on the street without looking for oncoming traffic relying on their ears and obviously not hearing a bike.
With more or less silent cars we are all going to have to be on our guards.
A ped stepping in front of a G Whiz is unlikely to even notice they've been hit.
