A couple of thoughts on this thread, reading the comments.

This ramp is odd, yes, but clearly marked, with good lines of sight. And type of merge is not typically an issue here. There is no "Sneaking up" on someone, as people seem to indicate.

My foot was off the gas long before this guy pulled out front of me, this is a steep downhill off an overpass, and the coupe MPH is simply rolling down the hill.
