Of course I, and most of the dads I know, optimise for something else: what’s the car that will keep me competitive, but probably losing, to the kids?

I don't. I need to keep winning until I can't to keep the boy in his place. He is getting closer every time. I know my day is soon to end, and a new house champion will reign.

I often use the wii wheel as my handicap for family, but my wife (new to games) is now good enough that I might need to switch that soon.

When my oldest was first trying Mario Kart, his uncle came over and played against him blindfolded (and still won). It was very entertaining to watch.

My trick is to just never power slide when I need to be handicapped to not ruin the kids Christmas. Or tap the accel A button in a PWM pattern.
