Its perfect on smooth roads.
Tires remain vertical during braking or launching as both tire move up at the same time.
Also no dangerous rear wheel positive camber when braking.

During corners BOTH wheels uppers turn to the inside of the corner.
Thus getting beneficial camber thrust from both inside and outside tires.
i.e. negative camber for the outside tire and positive camber for the inside tire.

Thus perfect so far.

The only drawback is on bumps.
Both wheels change camber, with an even more pronounced angle than a solid axle.
