Question about the motor

I want to ask, it would be too much to ask that the video game engine have vehicles by land, sea and air, such as cars, tanks, planes, helicopters, submarines, boats.

Vehicles can be made, and code can be made to do all these things, but lumberyard 1.28 is the final version of lumberyard unless it has a engine breaking bug then that would get fixed, all development has now gone to o3de, so I do not believe this will be added as assets you can drop into your levels.
