If it's possible: listing all the planned stops on a route or showing the route on a map before accepting the order. Currently, to see the route, you have to accept the order and view it in the scheduling menu. This is a little awkward. I feel it would save some (limited) time and in-game currency to be able to view these routes on a map, or a list of planned stops, before accepting the order. I know I would enjoy it as I cannot always guarantee availability of a bus for a given route (some buses will not get past some corners without damage due to vehicle size).
Second idea: Some sort of in-game info on the dimensions of each vehicle. This could be a small box in the menu when you click on a vehicle to view its condition. I don't always know how big a certain bus is by its model number alone, and this stat being available in-game and would help me in deciding whether to buy a certain vehicle or whether it would be unwieldly in most areas of the map.
