We're investigating ways to create a default speed for road types and hope to have something like that in a future release (current focus is on performance tuning so will be a while yet).

We're also thinking of having some keybaord shortcuts, for example Shift+Click might select all lanes on a road, etc.

As for bus lane colours, there's a possibility that at some point in the future we will have an option where you can select country/region and the roads / colours / traffic signs / etc. will change to match what is in that country/region. Was there a specific country or region you were thinking of and if so what colour are the bus lanes there?

Hello, thank you very much for your answers. It's nice :) I live in Belgium and the Bus lane is not in colour. Just "BUS" inscription. It's minimalist in my country. The compagny is "TEC" in Wallonia :) Good day to you :)
