Why are these mutually exclusive? An electric drive train can be fitted to an SUV form factor. In fact, it might be easier to get to an acceptable range (300mi) because there’s more space for more batteries (assuming each battery delivers more range than its weight continues to scale).

I think the easiest way to accelerate decarbonization is to make green tech more desirable independent of the greenness. If people want it, they’ll get it and in that sense SUVs could help achieve climate goals.
