Benjamin Kendrick has offered to pay a large amount over the death of Joan Johnston but not the full sum her widower is demanding in compensation.
Paul McGregor, the surgeon’s solicitor, told Perth Sheriff Court that negotiations were continuing between the two parties and the effect of Mrs Johnston’s weight on her lift expectancy was one of the factors being examined.
Mr Kendrick, 36, of Chesham in Buckinghamshire, admitted killing the morbidly obese woman on his way to a medical team bonding course in the Scottish Highlands during 2009.
He was fined £5,000 and banned from driving for three years but walked free from court partly because of his victim’s weight.
Sheriff Michael Fletcher ruled out jailing Kendrick because Mrs Johnston, of Scarborough, North Yorkshire could have survived the head-on crash if she had been of average size.
