The world is awesome and the music is an excellent fit. You both did a great job making the main character.
I have a few suggestions.
1. The player cannot back up
2. The mini map is hard to see -> have an icon for the player and the delivery spot. Maybe make the map a bit larger.
3. The vehicles need box colliders because right now you can go through the cars.
4. Ability to increase and decrease speed.
5. Penalty for damage
6. Bonus for getting delivery done on time.
This is a great start and I look forward to updates if you continue this project.
