Agreed, in principle. There is an intersection on my commute that was almost certainly designed to look pretty and break up the monotony of the grid layout with some elegant curves. Sadly there are accidents almost every single week, most likely because of bad sight lines and how much turning goes on. It would be nice for them to "fix the road" by just straightening it out but it would likely require a staggering amount of time and money because of how much infrastructure has been built up around it. The city has already tried what it can, so I think having the warning in the app is the best we can do in the meantime.
