I won't write a long essay about how to better integrate the car in CP2077 to be more than a vehicle, because it would be enough to implement one single gameplay feature to it. The stash. The car in CP2077 should be functionally similar to Fallout 2, a tool that not only allows us to move faster on the map, but it also functions as a mobile player stash where is possible to store excessive items (in the trunk). I propose this because I found the implementation of the stash in The Witcher 3 to be underwhelming, as it could've been implemented on Roach (using the bags that we can acquire as a method to increase the stash capacity instead the player's inventory) instead of fixed stashes on multiple locations.
