I sincerely doubt Rivian has any cars in the pipeline that aren’t SUV, truck, or crossover.
But yes, if someone’s gonna drive a fucking excessive vehicle, it’s better that it’s electric than ICE, absolutely.
Their pipeline is all smaller than their current R1S and R1T at least. I’d guess 5000 lbs for R2 and 4400 for R3. I hate these bloated vehicles too but weight should creep down as battery density continues to improve along with charging infrastructure. The problem is the culture (and the infrastructure and the non-existent pedestrian safety standards).
