the acceleration of the target output detected and tracked by the perception module is all 0

I would like to ask what the acceleration of the target output detected and tracked by the perception module is all 0 as the following:

This is one of the known limits of the map_based_prediction.

In the prediction, the vehicle motion is assumed to be a constant velocity due to a lack of acceleration information.

@maxime-clem Hello, sorry to bother you, I have a question about the predicted speed of static obstacles(https://github.com/orgs/autowarefoundation/discussions/5330), could you give me some suggestions? Thanks~
