IIRC the earlier work on roll-overs made the point that all cars have a resonate roll-over frequency that plays a part when drivers over correct a swerve. I wonder if anyone is taking a new look at that isdue. Also, whdn a bunch of combustion engines get displaced, what is therd to do with them beyond recycling the metal? Looks like the cost of these freed-up motors is about to drop. Motor futures; shorting anyone?
