Why is everybody saying it needs more vehicles?

This game is great! It has lots of things to do Like diving up roads or loading cargo but people get greedy and start saying we need more vehicles but there are plenty! The game is great and the people who play this app arent even seeing how great the game is already! So bravo, bravo developers GREAT game! Hope more great maps come out!
