Door opener

We are both handicapped My Wife has a hard time closing the door, It is hard for me to walk (bad back) to close the door. You make a device to close the tail gate door on SUV, vans ect. Why not for the front doors for Handicapped People, Women with small kids many ways this could be used.It would only work when Car is stopped and motor shut off.Attached to the key fob I am in the process of buying a new Fusion 2012 so please advise. and Thank you Billy Stimson
