Working Car Vroom

This is an app where you can play by watching the unique movements of each working vehicle.
There are various mechanisms that allow you to operate it simply by tapping on the icons and various things that appear.
Various vehicles appear, such as working vehicles such as power shovels, dump trucks, mixer trucks, bulldozers, power loaders, high-altitude work vehicles, pump trucks, garbage trucks, trucks, and container trucks that work on construction sites, emergency vehicles such as police cars, ambulances, and fire engines, and route buses and light trucks.
Tapping an icon changes the type of vehicle running in the center of the screen.
Tapping a vehicle will allow you to see the actions unique to that vehicle.
In addition, various types of vehicles will appear as passing vehicles, so tapping them will allow you to see some kind of action.
Occasionally, dinosaurs and UFOs may appear, so try tapping them.
Trains such as the Shinkansen also appear behind you.
