It is believed Walter Goto, 36, from Lords Close, lost control of his silver Mercedes and collided with the bank of the motorway, causing the car to flip, last Wednesday. He died at the scene of the crash, between the Watford and St Albans junctions, just before 3am.
Family members are appealing for witnesses to try and find out exactly what happened to their brother, a full-time art student and a “perfectionist in whatever he did”.
Sister, Ruth Goto, 42, said: “He was always smiling, he loved dressing very slick, and everything had to be the best. Everyone is missing him.
“He was known as an advisor in the family. He always gave advice to the young, and was a good role model to his nephews. To a lot of people who knew him, he was a man of many talents.
“He would put you first before his own needs.”
Mr Goto, who was born in Zimbabwe, is survived by four children in Harare, and an 8-year-old son in England.
Relatives described him as a family man, who loved dancing, documentaries, and drawing. He was both artistic and hands-on, taking great pride in decorating his home.
His sister Eunice Nhliziyo, 43, said Mr Goto had just finished creating a nursery for his nephew, who was born on the Friday after he died. She said: “He had a heart of giving”.
Mr Goto, who moved to the United Kingdom over ten years ago, was a former cameraman for the Zimbabwe Broadcasting Corporation. He was pursuing his dream of one day owning a production company, by studying technical arts and media degree at Middlesex University.
His younger sister, Lindah Wareman, 31, who Mr Goto gave away at her wedding last summer, described him as “passionate about film”.
Mr Goto’s long-term partner, Matshidiso Ratau, 28, said: “He was such a charmer, he used to say I was the most beautiful woman in the world. He was such a loving person.”
Family members wanted to let friends of Walter know, they are staying at Mr Goto’s home for the time being and anyone wishing to pay their respects are welcome there.
Mr Goto’s parents will fly over from Zimbabwe for a funeral, to join brothers Milton and Geoffrey, sisters Lindah, Eunice, Ruth, and Melissa , and partner Matshidiso, once the police have finished their investigation.
