Susannah Proctor, for Bhachu, told the court that her client was a “normal person who’s made a massive mistake”.
She said he “must live with himself in the knowledge of the devastation he has caused”.
And she said: “He did not intend to cause this devastation but cause it he has.”
Hulboj’s fiancé Dominik Czepczor watched the sentencing hearing in court.
A statement from him was read, which said: “My whole world collapsed in one second.
“Every day I feel a huge void after their departure.
“We had so many hopes and dreams and in one moment it all ended.
“My dream was to have a wonderful family, and I must say that it came true for a short while, but that was taken away from me on January 16.
“Unfortunately, all that remains are wonderful memories and a constant fight for the next day, which is not easy.”
Det Insp Paul Conroy, of West Yorkshire Police’s Major Collision Enquiry Team, said: “A woman and her young daughter have died because of the actions of these men, and I know no sentence will ever feel enough to compensate for the lives that have been lost.
“This sentencing hearing though does mark the end of a long criminal justice process for Justyna and Lena’s family.
“It is over two years since Bhachu admitted his part in this tragic incident and I know that the wait for justice has taken its toll.
“My thoughts are firmly with them today.”
