Cool project. Have you tried to implement articulating drawbar trailers[1]? The ones where the first axle of the trailer is fixed to the drawbar, making the front wheels turn when the drawbar moves. They seem to be much more common in Europe than in the US. In my experience, these are much harder to back up than fixed axle trailers.

The visualization of potential results is quite mesmerizing.

That was a lot of fun to play with.

I think the fractal solver is bugged, but maybe I am just using it wrong. It says placing a cone in the red zone will block the vehicle, but either the colors are inverted or the backend is off, because everything is red except a few spots.

Otherwise very fun. I managed to park a truck the solver called impossible :)

Note: Using safari on an iPad of that matters.

This is pretty fun!

Is it actually solving anything though? It always seems to get stuck with the semi half sticking out.
