There is an intersection in my neighborhood that has had so many accidents, they put that same sign up.
Of course, all the accidents have been caused by people running the stop sign (and not looking). The through street is a long curve, so you can't see very well in one direction.
I live on the curved street (in that direction) and am always careful some dickweed doesn't hit me (running the stop sign, and the warning that it's not a 4-way stop) at that intersection.
And since the covid has resulted in almost zero police patrol in my area for 18+ months, many people now think 45 is the new 25.
But what NOBODY wants is those stinking speed bumps all through the neighborhood. They have put some over on a main artery to the neighborhood a few blocks away, and if you didn't have your seatbelt on, you'd hit your head on the roof, even at 25. I go the long way round, just to avoid them.
