Years
ago, I worked the midnight shift at a gas station off the interstate outside a
small town. The town basically shut down
at night. Many nights I’d go down main
street without any other cars, not even parked ones. But there were other nights I’d get stuck at
a red light that was on a timer. I’d sit
there for over a minute almost screaming, “There’s no f---ing point to this!”
But if I lived in a world where everyone had an autonomous car, the car would
get on the self-driving chat network and ask, “I’m approaching Intersection
15743486N. Is anyone else approaching
it?” When it found out no one else was coming, it would just zip on through; no
fuss, no muss.
Of
course, that makes sense for intersections in the middle of the night in a dead
town. But what about intersections with
lots of traffic? Currently, the
north/south lanes stop so the east/west lanes can go. But in a world where all the cars can talk to
each other, they’d work out the timing so that there would be gaps in front of
and behind every car that would be wide enough for the cross traffic can go
through. At first, these gaps would be
rather big because if you’re zipping along at 50 mph and another car passes in
front of you with just inches to spare, it would give many of us old-timers
heart attacks. But as the generations
got used to the idea, the gaps would become smaller, until cars passing within
inches of each other became normal. Or
maybe, instead of windows we’ll just have screens so we can watch movies as
we’re driven to where we’re going.
What
about pedestrian crosswalks, you ask? If
you’re redesigning a city to take into account autonomous cars, then you’d
probably have pedestrian only zones and to cross out of these there would be
bridges over the roads. Or the
crosswalks may end up on a timer and all the cars would factor those in as part
of their route selection. Thinking about
that, that might be a tad eerie. You’d
be walking up to a crosswalk and cars would be zipping by, then the crosswalk
light would come on and the traffic would just disappear, as the cars turned a
block away to go around this crosswalk. You’d
cross the street, and after a couple minutes, the crosswalk light would go out
and the traffic would all come back. On
one hand, a testament to coordination, but on the other hand that seems so
unlike what people in cities are used to, that it would take time to accept
that as the new normal.
