Neat!

looked at using airsim a few months ago to replace a product we'd been using for some time, problem was the actual vehicle dynamics simulation capabilities were subpar

Did not do a code review but I would not be surprised if they were using Unreal's default vehicle simulation; which, as you noted, is indeed sub-par. It's honestly a very challenging task to get vehicle physics to accurately replicate real cars, and the systems which are out there (commonly used by manufacturers to make advertisement renderings) are proprietary and expensive.

Awesome; it looks like GTA gone serious.

If using Unreal, the assetto corsa competizione video game is pretty good for simulations and it offers a commercial license. https://www.assettocorsa.net/assetto-corsa-pro/

As does rFactor2 but it may not be so easy to use with unreal.

It the demo video it popped up"Advanced Physx car model". Physx is designed for a good enough approximation in games, not an accute simulation.

If you are interested in this, I would recommend checking out DroneSimLab [1]. Both are developed for the Unreal Engine and both have SITL (Software In The Loop) for drone control. One thing DroneSimLab will allow you to easily do is add multiple drones. If I remember correctly it uses Gazebo to create semi-realistic control for the drone.
