How to Train an Autopilot (Donkey Car)

I’ve read this guide & would like to use this as an exercise for college students. However, I don’t have a background in AI. Can anyone provide insight into how the driving skill of the AI will be impacted by the following?

1. The shape/length/complexity of the track that is used to collect training data

2. The quality of the training data, for example how well the human drives the car while recording the data

3. The choice of Keras model from these options: http://docs.donkeycar.com/parts/keras/

Edit to add additional context: I’d like the students to build some intuition about how these factors will impact the AI training process so that they are able to propose an economical training plan. These will be industrial engineering students, so they’ll be focused on improving the training & car assembly processes rather than the software engineering behind AI.

Thanks!
