This Lincoln MKZ with New Jersey license plates was spotted on Saturday, May 22nd, 2021 at around 8:40am on Zanker Road in San Jose.
Any hints about the company behind that test vehicle is highly appreciated.
UPDATE: Users point out that this is a vehicle operated by Nvidia, as also shown in this other video.

I saw the same vehicle a few weeks ago. A former Nvidia team member said the vehicle belongs to them. I also saw another similar vehicle in San Jose that appeared to be mapping or verifying map data https://youtu.be/ombONeQ8few
