I think the signs are just fine the way they are - It's the drivers that are the problem! You're right - the biggest problem is the 'ignorant/aggressive driver' followed closely by those that don't bother to read the signs. Let's face it - if you accidentally got into the turning lane, make the turn then go down a block to St. Mary's parking lot and turn around! It's not that difficult a concept! Maybe what we really need is a police officer permanently stationed at that corner.
