## Note: this is deprecated. jq is still awesome, so now we just get JSON all the way


# jq JSON parser is awesome:

# The NHTSA API is pretty clunky, requiring you to get a list of all the years, then all the models in that year, then all the makes per model, and then
# finally, you get the vehicle IDs needed to query the endpoint for one vehicle at a time.
#
# I query for JSON for most of the loop, and in the end, I get the Vehicle data in CSV format

# Note, there are a lot of errors in the API, because the NHTSA doesn't properly escape the "/" in a car's name. And many other
# whitespace related errors.
