Vehicles parking over pavement, reducing the width of pavement, especially for wheelchairs and mobility scooters

The houses in Mill Road are using their gardens as parking spaces, but their vehicles over shot the pavement, causing an obstruction and narrowing the pavement substantially, there is no pavement on the opposite side of the road in this park of Mill Road, the reduced width caused would impact on wheelchairs and mobility scooters. I just don't think this is right !
