Everything you said is absolutely true.

> Relative to other "standard" offroading 4x4s like the Rubicon/Wrangler or Land Cruisers, the Rivian is at best average and the Cybertruck is decidedly worse

But it's pointless to compare the Cybertruck to a Wrangler or Land Cruiser. It can tow more than 3x as much, payload is more than double, it can seat five people and still have a hug amount of cargo and of course it's way, way, way longer (and wider).

It only makes sense to compare it to an F-150, Ram 1500, Rivian, etc.

In which case it is really not bad off road at all.
