He was homeless but ended up getting hired as an engineer because of an idea he had while he was homeless.

an interesting idea, but it raises a lot of questions:
if its so foggy the bus driver cannot see people standing at the bus stops, should the bus be running at all? or is the driver going too fast for the conditions?
how does the bus turn the light off when it picks up the rider?
How often do kids walking by hit the button, just to be annoying, like they do with elevator buttons or street crossing buttons, and then walk away?
what if there are several lines running past one stop? how does the rider signal which bus (route) he wants? do all the busses have to stop until the right one comes along?
couldnt riders along foggy routes get a 1$ AAA flashlite to flag the bus down? Wouldnt it be cheaper for the bus company to give away $1 flash lites to regular riders than to put $2000 solar powered signals at every bus stop?
Maybe the bus driver DID see him but didnt want to pick up some homeless guy who looked like a bum?
If its so foggy all the time how does a solar powered device get enough energy to operate? wouldnt it be better to use deep storage batteries, like the Coast Guard uses on bouys?
Ok, Im done playing system engineer - its a clever idea, for some areas, under some conditions - and Im glad to see this guy pulled himself up out of a bad situation by thinking of a way to solve a unique problem :^)
