There is the possibility that this could result in more red-light running instances, if runners begin to presume there is this collision warning system. Whereas before they were "taking chances", now it'd become less "chancy".

I wish it would explain how the accuracy numbers work. I could say 'no' to every car and get pretty good naive accuracy, so that's clearly not the method they're using to give the old models scores of only 15-20%.
