The number of times I've been almost hit by a Tesla because I was walking in a parking lot and didn't hear them (because they didn't have any warning sounds) is too damn high. If they're going slow, they should play a sound or something. I check behind me, no cars, I cross the parking lot road, only to be almost hit by a Tesla because they just pulled out, and I didn't hear them. A simple sound, whooshing, beeping, whatever, would have solved that problem. Why Tesla didn't implement such a thing is anyone's guess.
