The Bishop of Bristol's wife, Anthea Hill, has returned home after spending seven weeks in hospital.
The pair were travelling back from Slough when the accident happened
Mrs Hill, 61, fractured her neck when the car she was travelling in veered off the M4 and hit a tree.
The news was posted on the Bishop's "blogsite" which has received 81,000 hits from people wanting to check up on her progress and send messages.
Doctors say Mrs Hill is making "slow but sure progress", and can even take a few steps.
It is hoped the couple will be able to receive visitors in the New Year.
The Right Reverend Michael Hill, 57, broke his shoulder in the accident on the M4 in Wiltshire, on 1 October.
In a message on the blogsite the Bishop's communications assistant, Oliver Home, said Mike and Anthea were "...looking forward to this massive leap towards a more normal life" after returning home.
He also said the Bishop wanted to express "...the depth of gratitude that he and his whole family feel to the thousands of people who have prayed, written and supported us through this really difficult time."
