you can be looking straight ahead and still not recognise the car in front is stopped/going slow. its all about perspective and whether an object moves/grows/shrinks relative to the last time you looked at it
its one of the reasons people dont see bikes, the percentage difference in size doesnt change much until its very close, by which time its too late
if the car in front isn't moving left or right in relation to your head, you don't see its stopped until it gets much closer, at 70 mph that doesnt give you enough time to process the new data, take foot off accelerator, move across and stamp on brake
