Fr8i: I posted this in SCS forum a little while ago. Do you think it is something you would concider for future versions? It should be a very easy tweak, which would do a lot for realism

"One thing I would love to see in Southern Region: The low bridges, pipes, trainlines etc that are marked on map and by sign as 4,5m, 4m or even 3,5m are clearly WAY higher than that, usually around 7-8 metres, sometimes even closer to 10 metres. This is also the case with other russian maps, like RusMap, but you in Southern Region have the added feature of height warnings on the map, which would make for a very interesting addon if they were actually real.
A 4m underpass would usually be fine with a normal full cabin and curtainside trailer, but only just (probably 10 - 20cm clearing because of margin of error on signs). Any higher trailers, like silos or high box trailers (perhaps even some container trailers) may have trouble with 4m underpasses. Sometimes it will work, sometimes not, again, because of margin of error. Driving such trailers, you will have to concider if you are willing to take a chance and risk having to reverse back to nearest crossing or turning area, or if you choose to plan ahead and take an alternative route. Some passings may have local alternatives for tall trucks, others may require longer detours.
A 4,5m underpass will be good for most trailers (10 - 30cm clearing to the highest high box NTM configurations), but may require detours for special transports.
A 3,5m underpass will require low cabin trucks with low trailers, like empty flatbeds, open trailers with low pallets (like the brick trailer) or perhaps some tank trailers.
Of course, there could be underpasses at any different height between 3,5m and 4,5m, allowing for different truck / trailer combos making it through or having to take a detour.
I would absolutely love to see this actually featured (not only pretend-featured) in some map at some time in the future, as it is a very real thing for real life truck drivers like myself to take into concideration. I am always very excited when I see height signs in ETS2 maps, and always equally disappointed when it turns out the gap is actually litterally twice the posted height."
