With this new cheap driving through pedestrians terror technique to inflict maximum carnage, like in France, Germany, England, Sweden and now New York, people everywhere need to be very much aware of the danger around them in public spaces and to be extra careful of all vehicles, especially during high tourist season with large crowds in the streets. Also, cities need to take very seriously their responsibilities of better protecting the population with much more safety measures and physical barriers like in Time Square, where those security street stanchion, finally put a dramatic stop to this massacre; too bad there was not more of those, as it would have stopped the madness much earlier and saved more lives. Sadly, an 18-year-old girl died on the scene, and at least 22 others were injured, some very severely.
Down the road, car builders could be forced to put remote control shut down devices in all vehicles, which police and other authority could use at will, to avoid long unnecessary dangerous high risk chases. (Just an idea, but very feasible)
