Absolutely! This manages to land in that cozy little niche of "pretty cool, despite the issues." Your commitment to the idea was admirable, even if it needed more time to bake.
Regarding the car physics; I'm not exceptionally familiar with 3D development, but looking back, do you think it would have been a more scope-appropriate solution to remove the physics causing the fish-tailing and hand animate the car moving between a set of fixed lanes? This is likely how I would have done it in 2D, but I'm not actually sure how feasible it would have been for you.
I think I can see the arguments for not including the speedometer: practical reasons like having to create a frame of reference, make the assets, and implement it on a project that had elements that were already taking more time away than you had intended, but also thematic reasons, such as the fact that a passenger isn't normally preoccupied with most dashboard readouts. There's probably a middle ground; maybe indicating speed increases via non-HUD visual flourishes or something. Something to tuck away for next time, I guess!
