Any idea if you can enter your own homebrew system? I mean, the hardware listed isn't really all that special. You could probably take this:

Slap it on new-ish Samsung or Apple phone, coupled to a cheap-ish RC car...

That'd probably get you 80% of the way; also, check out NVidia's "End-to-End" self-driving vehicle paper:

I built a tensorflow model from that trained on a 750 TI for the Udacity Self-Driving Car Engineer Nanodegree (it was part of the course to build such a thing that ran on a virtual track), and after training it did quite well - at least on a virtual track.

A few tweaks to the model, maybe using the TensorFlowLite package or something on the phone - probably work fine for 99.9% of the runs...
