I have come up on a car that was parked on the road, there were no brake lights or flashers on the car and it took my brain a while to catch on that something wasn't right, first I thought it was just going slower , by the time I figured it out I did not have time to stop and ran on the shoulder to not crash, then came to a stop..the car behind me did the same thing
your brain just does not expect a car with no brake lights to be stopped on the road
