No Left Turns

No it is not a political statement, It’s a safety demand.  I just read in the paper today about another child killed in crosswalk. We, the human race needs to understand how the human mind works and build our society to allow for our own foibles. For instance, it is difficult for a person to do two things at once, in this case watch both on-coming traffic and the pedestrian crosswalk. It is difficult for the human mind to remember to check for things that don’t happen very often, in this case, pedestrians in a crosswalk. People should walk more and in places where they do it is probably safer on a pedestrian mile basis but in places where people don’t look for pedestrians it is more dangerous. Humans fatigue. No matter how good of a driver you are you are worse when you are tired. For the purposes of this argument lets leave out impaired or distracted. 

What is the Science Fiction Land solution. First, it seems like a simple thing to make GPSs with a as few left turns as possible feature.  Second, there are probably some traffic flow changes that can be made. Just as some cities make a decision to go with lots of one way streets and people need to get used to it maybe there is away to design cities with few left turns. Third, self driving cars. It would be be standard practice to program a self driving car to watch both on-coming traffic and the crosswalk all the time every time.
