If this did become a problem police would use targeted enforcement to deter selfish idiots from stopping traffic . It would take a little time but people would learn . Aside from this , as driverless cars become more common , traffic speeds will increase and stopping at intersections for cross traffic will just no longer happen . I suspect that we will see pedestrian over crossings become ubiquitous at some point , just to insure that traffic can move at top speed . <| sep |> Yes , you weirdo . <| sep |> First thing I would recommend is reading . Read everything you can get your hands on , about the system , requirements , agencies in your area , children , and fostering in general . Local agencies can help a lot with resources and advice . You may be allowed to start on the required training now , but that ' s not guaranteed . Your husband has to be onboard 1000 %, saying that ' s her thing , I ' m not involved will result in an automatic rejection . Make sure you have a stable support network of family andor friends , they like to see that and you will need it . Start building good and stable relationships now . You can choose an age group , but you may be waiting a while if you ' re intent on being strict .
