I have seen similar.
Here in Albany, NY, at the intersection of I-90 and I-787, when getting on west 90 off of north 787, there is a very tall ramp, at the top of which is a sharp turn that is insufficiently banked, with much darting back and forth to bet between the lanes for eastbound and westbound.
A couple of years ago, an electronic sign planted there was displaying a message.
Was it telling me that there was an accident ahead? No.
Was it telling me that there was congestion at the I-87 interchange a few miles away? No.
Was it telling me to tune in to the TIS station on 1610 AM? No.
No, the message that they decided was so mind-numbingly, gut-wrenchingly, earth-shatteringly beyond urgent that it required me to take my eyes off of this very dangerous intersection was.... speed twice in work zone/lose your licence.
Fucking brilliant.
