So, if you make a quick stop and get out before the vehicle comes to a complete stop and after unloading/loading the truck and if you return to the driver's door then the option to get in first is replaced with the option to open the trunk first. The error is not critical or very irritating because you have to scroll to select the option to enter the vehicle.
