I was looking at what RC cars are doing and I know one of the hot additions to these playthings is a chip-based gyroscope that aids in handling by correcting steering.
I suspect the gyro chip is responsible for RC cars literally flying in the air and adjusting themselves to land upright even if the RC car is coming in one-wheel first. The dynamics of how these toy cars operate literally crazy. Here is a video of some top RC cars. I point your attention to the last one (5:05) as it is basically a three-wheel design, the moves of which are outrageous and somewhat suggestive of what could be availaable on a tricked out Aptera.
It could well be that Aptera has included a gyro chip and just calls it stability control ... because that is what the gyro chip helps with on an RC.
I know the weights and physics of a full size vehicle like the Aptera involves a lot greater forces because of the relative masses, but we also know the Aptera's GVW is a fraction of other cars and, at least its monocoque composite body is dramatically stronger as well.
Oh, and the promise of off-roading is not necessarily limited to slow crawls over boulders but leaps off dunes at speed... and the Aptera is already designed to do off-roading.
Logically, this would suggest the Aptera is capable of some mighty, mighty stunts, especially with its torque-vectoring drive system. Completing the if-then sequence, how many Aptera's do you think Hollywood will grab when there looking for 'starring' car when someone makes a remake of the TV series 'Knight Rider.' (When you think of the AI tech from Siri to the current state of the art of self-driving - the capabilities of KITT - the fictional intelligent car in the series - could all be incorporated in an Aptera for real. That's how far we've come and we don't even realize it.
I have heard that it does, at least in the early planning stages
