And I'll get my ole' diesel rights back here from Waynne (sorry).
Such fun to let 'em think they're making progress alongside up til about 60-70mph. Then boot it (any gear - mapped up modern diesel, it doesn't matter which you're in) and watch their silly little cars disappear into the distance in the mirror.
Ok, they sometimes catch up a few miles later but it's taken 'em ten minutes to do so. So, repeat over -- toe down, byeeee |
