Firstly, NA Williams is a company that provides marketing/data analysis/consulting services to its clients (autozone, oreilley auto parts etc.
http://www.nawilliams.com/customers/). It does not produce the car parts. As it has been pointed out before all these downrampers flooded this forum, NA Williams, as part of its service would market the GSW last mile logistics solution to its clients which is how both GSW and NAW was most likely able to come up with a rough indication as to how much revenue it would be able to derive as NA would have collated the data over many decades. Just google autozone - they are enormous.
Secondly, I welcome difficult questions being posted but when the questions are poorly researched or just plain stupid that is what is frustrating. Ive followed GSW for quite some time and the amount of non-holding downrampers that have suddenly appeared is astonishing. Misinformation after misinformation being spouted here - all of which just drives fear into people.
Agreed that they need better communication to the market but i think the combination of the demand for the last mile solution (see
https://www.mckinsey.com/~/media/mckinsey/industries/travel transport and logistics/our insights/how customer demands are reshaping last mile delivery/parcel_delivery_the_future_of_last_mile.ashx) and the strength of the product is what will prevail in the end.
