Here's something I've always wondered. WHY are some highway and route exits so damned short? Don't know if they are like this in other civilized parts of the country, but here in NJ, we have exits that barley give you 2 seconds to merge before heading off into another exit turn. I know highways where constructed back when a cars top speed was 30 MPH, or there abouts, but this dosn't include new highways constructed in the last 30 years or so. Anyone have an explination for this? Makes a hell of a headache for those of us in the slow lane trying to avoid cars making the quick merge .
