“Terrible and annoying”? Well, not to me, beauty is in the eye of the beholder and all that. My garage is built right on my property boundary, exiting directly on to the footpath. Reversing out of my garage would be a significant pedestrian risk without the so-called “annoying” beeping - which as soon as any pedestrian hears it, knows exactly what is going to happen next. So there.
And considering people barely reverse for more than a few seconds, how “annoying” can those noises really be to anyone?
As to “The Tesla solution is much better” - they have a more noise-like than whine-like forward alert sound. I’m curious as to how is that “much better”?
