If you take a look at any current door opening/closing animation, most of them just open with a linear speed and end abruptly. For example, the class 710 doors open with a higher speed and then slow down towards the end. https://www.youtube.com/shorts/hjHIRH6fCyA This probably isn´t really that noticeable, especially when you are driving, but it would add a bit more realism if the door animations would be recreated closer to the real life ones.
