If you're interested in seeing how big the R1T is next to a Model X, here's some photos taken outside of the Rivian factory in Normal.
No doubt it is a Model X. But, one can be forgiven for thinking it was the smaller Y based on how the Rivian towers over it. I always though the Model X was a pretty good sized car. Still amazed at how much bigger the Rivian looks. Based on the reported dimensions and reviews stating it was between the size of most Full Size and Mid Size trucks, certainly didn't expect this.Also, the open slot "grill" on the front is S/X, the 3/Y has no grill.
