% GM has several decades of experience keeping the spying media at bay, that
Google and Apple have not seem to practice (lots of Google and Apple pr,
bragging, spy-shots, about them but nil about the Bolt, etc.).
Because GM did not let it be known, nor the media able to spy all of GM's
Bolt testing, does not mean one should assume GM does not extensively test a
new product before putting into production. GM knows from experience that
well documented testing can come in handy when they are called-on-the-rug
for issues that come up later ('Our testing did not show a problem', etc.)

How GM Is Conducting Final Testing Of Its Bolt EV ...
JUN 13, 2016 ... When incumbent automakers develop new products, vehicles go
through three major phases of testing. The first phase is component or
system development on cars that are typically referred to as mules. New
mechanical and electronic parts are installed on older generation vehicles
to accumulate miles in a real-world environment that exposes these systems
to the temperature and vibration conditions they might experience in the
hands of a customer. There may be dozens of these mules accumulating test
miles for a year or more before prototypes that look like the production
model exist. Parts for the Bolt were tested in Spark EVs and Volts.
The next stage is the integration prototype, the first variant that actually
starts to look like what will be sold to customers. These integration test
vehicles include virtually all of the parts that will go into later
production examples and are generally built from production tools. These
vehicles usually appear 18 to 24 months before production start. In the case
of the 2017 Chevrolet Bolt EV, almost 100 integration test vehicles were
built starting in early 2015.
These integration test vehicles go through a staggering array of tests to
make sure everything works as intended and continues to work over the
expected lifetime of the car. For most modern cars, specifications call for
most parts other than wear components like tires and wiper blades to survive
10 years or 150,000 miles. To ensure that happens, cars are run through
foot-deep baths of salt-water hundreds of times, passed through car washes
500 times, exposed to hurricane-force rain chambers with water pouring down
at 2,000 gallons per minute and driven tens of thousands of miles over
cobblestone and dirt roads to try to shake everything loose.
The final stage is the so-called captured test fleet. About six to nine
months before regular production starts, the tools are moved from the test
lab to the assembly line and the workers that will ultimately build the
customer cars build several hundred pre-production units. A few of these
cars show up on auto show stands and are used for marketing photoshoots. The
majority of them go into durability fleets where they are driven round the
clock to accumulate miles in variety of conditions and into captured test
fleets. For the captured test fleets, company employees are giving near
final pre-production cars to use as daily drivers for two to three months
