It's a stretch of road, that makes you want to throw yourself along it at high speed to cause as much scrape damage as possible.
Like, the compulsion to do so only increases the more you are on said stretch of road.
it just, became active one day and since then an increasing number of accidents have occurred.
Effect is persistent regardless of means of transport, be it foot, bike, car, plane, misc vehicle. if you have any control what so ever you will try and find a way to grind your body into road paste at high speed.
