The way I did it was that I drove for other companies until I could get 500k from the bank. Then I just bought 3 Renault trucks (around 100k each) and upgraded my garage to house 3 trucks and drivers. Both of them now make around 1k per day and are leveling up nicely. My own dude makes around 20k per day so just a few more jobs and I can expand the empire with a new garage
Also, here are some screenshots of a very messy situation somewhere in Germany:
#1. Had been stuck like that for a good 3-4 minutes.
#2. The view out of my window. A truck was stuck at a junction and they're just not assertive enough in this sim to claim their space in traffic :<
#3. The view of the situation after I had... convinced one of the cars to (how shall I put this...)
move aside in order to let me go about my business.
