Not that I know of, but could be? Amazon was the first to sign a deal with them for delivery vans though. But Fedex, UPS and others have since signed as well.
I did some consulting for Rivian back when they were a start up, before they were even called that. Their prototype was an Ariel Atom with their electric motor, but they showed me the van too; this was ~10 years before it was released. One of their GIS people was let go and she left the server with their data locked and it was not being backed up. They could work still, but their data was sort of in limbo and at risk. I worked with the vendor and got them up and running.
640HP in 10 second bursts on launch
Pricey, but I would say a bargain for what it is capable of. Most EVs are quick, and this one certainly is, but few also handle the twisties well. Two Pike's Peak records last year means it can do it all. Not exactly what I would call a daily driver though lol.
