you can get is pretty thin in terms of
what you can do with them and the
ability to extract meaningful
information at scale. Most fixed
sensors are very localized and to
cover a city you really need to make
a large investment, which is
considered a one-off, but then the
information you get deteriorates
because they malfunction, which is
a very hard problem to fix because
they’re buried in the road. Even
when they are working you
typically get a very limited
set of information. It’s
almost impossible to cover
every junction with fixed
sensors whereas taking
a sample of vehicles that are
moving actually colors
a whole city and allows us
to build robust models.”
