2020: My Country

Each building that has vehicles can have up to three vehicles. You start with one, and others can be bought with cash and an employee (needing parts from jobs). So, technically you will need to get far enough into the game to have ten vehicle buildings, which is quite far in. Thankfully there is a another little glitch that makes this really simple - in fact you could do it with one building with a single car.

1 - Click on the cardboard box icon (this is the warehouse)
2 - Click on “Pick Building”
3 - Click on your vehicle building, then when asked if you want to move it, select “Yes”
4 - Click the tick to confirm
5 - Click on your building and hit “use”
6 - Return your building to where it was

Each time you do this, any vehicles in the building will add to your count. Of course doing this with a building or buildings with three cars will make this faster.
