Bingo! Got the real data from the DOL:
Linda forwarded me your request since I work directly with the Department of Licensing (DOL) to collect the qualifying vehicle count.
From July 15, 2015, through June 30, 2016, sales and leases of vehicles powered exclusively by clean alternative fuels and plug-in hybrids capable of traveling at least 30 miles using only battery power were exempt from sales and use tax if the sales price of the vehicle was $35,000 or less.
Starting July 1, 2016, sales and leases of vehicles powered exclusively by clean alternative fuels and plug-in hybrids capable of traveling at least 30 miles using only battery power are entitled to a sales and use tax exemption of up to $32,000 of the selling price of the vehicle or total lease payments made. In order to qualify for this exemption, the vehicle must be on the list of qualifying vehicles as determined by the Department of Licensing (DOL). (The list of qualifying vehicles can be found at
WA State Licensing (DOL) Official Site: Alternative Fuel Vehicles and Plug-In Hybrids Washington State Tax Exemptions.) The exemption expires after the last day of the month following the month DOL notifies the Department of Revenue (Department) that 7,500 vehicles qualifying for a sales or use tax exemption have been titled since July 15, 2015. (For example, if DOL notifies the Department in October that 7,500 qualifying vehicles have been titled since July 15, 2015, the exemption expires December 1.) The vehicle count includes both sales and use tax exemptions in effect since July 15, 2015.
2,334 qualifying vehicles have been titled from January 1, 2017 through June 30, 2017.

Doing the maths, the current count of 5,029 minus 2,334 = 2,695 as of Jan 1. At approximately 2,500 per 6 months, it looks like 7,500 will be hit by December for a Jan 31 cut off. I would assume rapidly increasing numbers of Bolt registrations in the last 6 months of the year. How do we get this information to Tesla since it seems like they did their best to accommodate WA Tesla customers? I'm far away from a WA Tesla dealer, can people bring it up every time they interact with Tesla?
