What is the impact of a motor vehicle accident on an income stream?

43 The frailty of starting with an income stream was stated by Mr. Justice Taylor in Ilic v. Fleetwood, supra, at 277: Calculation of loss of future earning capacity on the basis of present value of total future earnings at pre-accident rate to normal retirement age, less an allowance for contingency, seems to me inappropriate in cases of this sort. To proceed from the premise that the plaintiff would, except for the accident, have continued in her former work to age 65, and that as a result of the accident she would not work at all beyond the age of 45 -where the evidence does not support this as anything more than a possibility - and then to reflect what must be regarded as more probable alternatives in the form of a contingency allowance from the figure so arrived at, must in my view tend in the present circumstances to overstate the loss.
