Unfortunately, current cars have to be controlled by humans, and the human brain has certain characteristics (selected for by evolution) that makes it near impossible for it to be able to react to 100% of the driving situations. There are built-in efficiency circuits (similar to CPU branch prediction) that takes immediate action based on what it typically sees. So if 99.9999% of the time, when a car in front starts to accelerate, and doesn't slam on the breaks immediately after, the brain makes the assumption that the care in front will never slam on the breaks and devotes less brain-CPU time to "Oh No, that care in front just slammed on the breaks" processing. In general, human drivers don't do this unless they are very inexperienced. You don't mash on the gas and immediately mash on the breaks, instead you make sure there is nothing coming. If you can't see well enough that there is something coming, then you ease up slowly and only mash on the gas when you have enough information that you won't get side swiped going through the intersection. And yes, intersections that have a "stop line" far enough back that you can't see cross traffic are poorly designed. Or if cars are really expected to stop every time before a crosswalk, then advance 2 feet to stop again, this needs better enforcement so that activity becomes normalized to the point where the car behind would expect that (one way of doing this is to put two stop signs, one before the sidewalk, and one at the intersection).
