EVs are indeed very quiet, making them sometimes hard to detect by noise in my experience. Not even necessarily on the road: Around here hedges at the front of houses are very common. With ICEs you can usually hear that there is a car on the driveway with the engine on when you walk past so you can be careful. Now with EVs suddenly there's a car popping out of a driveway without notice.

EVs also accelerate much faster than ICEs. I often see EVs accelerating like crazy in traffic or at traffic lights and junctions.

I think there will be a period of adaptation for all road users.
