Dolores McNamara, 56, who scooped €115 million (£97 million) in 2005, obtained €8,401 (£7,110) in a compromise settlement after her Mercedes was "extensively damaged" in the prang.
But the cash is less than half the €20,000 the Limerick, Ireland, mum-of-six earns in interest on her mammoth jackpot every month.
The settlement at Killaloe District Court in Clare - temporarily sitting at the Brian Boru pub in Ballina, Tipperary - is a drop in the ocean compared to Ms McNamara's current estimated fortune of €121 million.

It is understood that the principle involved and to have her position vindicated - rather than the money - was the issue for Ms McNamara in suing William Butler over the collision where her Merc sustained "extensive material damage" on October 27, 2015.
Evidence was due to be heard before Judge Aeneas McCarthy yesterday but when the case was called, solicitor for Ms McNamara, David Scott, said that talks were ongoing outside court and asked for more time.
Shortly after, counsel for Mr Butler, Sandra Barnwell BL, returned to court and told Judge McCarthy that "a compromise has been reached".
The settlement spared Ms McNamara - Ireland's 117th richest person - giving a sworn eye witness account of what happened, the Irish Mirror reports.
Mr Scott said that an order in the amount of €8,401 could be made in favour of Ms McNamara, plus costs, including an engineer's report.
No admission of liability was made in the case.
Fiercely private Ms McNamara sat at the back of the courtroom while Judge McCarthy heard other cases on the list and as she left court at the end of her case, she turned straight back inside, so avoiding being photographed.
She later left through a side entrance of the pub without being photographed.
Ireland's richest Lotto winner lives at Lough Derg Hall, Ogonnelloe, close to where the mid-morning collision with Butler's white commercial Ford vehicle took place.
It is understood that neither she nor Mr Butler was injured.
It is believed that Mr Butler's vehicle came around a bend and Ms McNamara had pulled in her car alongside a ditch and was stationary in an attempt to avoid a collision.
It is not known the level of damages that Ms McNamara was seeking as a result of her civil action.
However, the maximum amount of damages that can be claimed in the district court is €15,000.
