Annoying Car horns – Can technology ever replace vehicle horns?

My street empties into one of the biggest and most jam-prone avenues in the city. During certain times, traffic backs up on my block too, and people sit outside my window leaning on their horns.

We also get the same effect at random times of day whenever anything larger than a sedan (often a truck so large it probably shouldn't be on the local streets in the first place) gets stuck behind a double parked delivery van or renovation contractor's truck.

Even while travelling, if you are passing by larger than sedan vehicles, it becomes unbearable.
