Alright, after some playtime with it, its really smooth and natural feeling (as far as factorio controls go anyways) however, it seems to struggle on sharp turns (specifically 90 degree turns). I know this is in your description as a weak point for this mod, but maybe you could implement some kind of response when a turn above a certain degree angle is approaching and/or an abrupt stop? I would be thinking along the lines of a warning symbol/noise. This way players have time to react if they don't realize/forgot that there is a sharp turn or sudden dead end.
Otherwise, this mod is very good. I also love how the cars stay in their lanes. Very nice touch with the Asphalt compatibility. Which also brings me to the suggestion of a parking assist as well? I understand that would be more difficult, but just some food for thought.
