Get a few garages and drivers two garages and maybee four drivers for this to work quicker,get them out on the road earning, go to one of your garages and swap lorries with one of your drivers this will move time on quickly which means anything your other drivers earn will go straight to you, keep swaping as much as you like. works with as little of as many drivers you can have only having more drivers means your money will go up quicker(more drivers more money). I do it with seventy drivers working and can make up to 2,000,000 for just a few minutes work great.
