Hoodies playing chicken...?
There was one Zebra crossing in the Chapeltown area of Leeds where car-jacking was common (typically of cars with single young and/or female drivers, but I recall one report involving an elderly couple). One guy would walk out on the crossing in front, then the least done was bags from passenger seats nicked through an open window or by opening the passenger door, but the one with the elderly couple was where two guys jumped in the back seats when the car stopped, forced the driver down a side road before ejecting driver and passenger out of the car and making off with it. In other countries the outcome might be more lethal.
It wasn't the only place that this sort of thing happened, and part of the the response was to adapt the tech that created the situation. Drive-off auto-locking became popular in cars that had central locking fitted, and the Chapeltown crossing was altered to a Pelican one that changed the priorities. However, if self-driving cars are set to automatically stop for pedestrians straying in front of them, then any suitable spot could become that Zebra crossing.
Obviously we can't have cars just mowing down peds all the time and never stopping - some places might be bad, but it's not quite got to the original Deathchase 2000 - so what's the tech response? Especially in cars like the Merc F 015 concept and the Google pod where the driver is the car.
