I ' d take hemorrhoid every day over a hernia just sayingEdit I thought about it , I sit a lot . Fuck both of them , which proves your point I guess . <| sep |> Smoother curves . It ' s not very realistic to have sudden sharp corners when you don ' t need them . On top of that , it makes traffic slow down aggressively , which may cause traffic jams on otherwise not congested roads . This is especially apparent in some of the freeways , where it seems things were thrown down without thinking the whole path through beforehand . It ' s important when putting in interchanges to adjust the highways so they line up gradually and smoothly , rather than making a super tight Sturn right before the asset . More Unified Grids . When building grid or semigrid cities , it ' s important to ground your networks around some core , consistent pattern . Even if it ' s just a single street going down the middle of an area , having it follow cardinal directions or terrain makes the rest of the grid seem like it grew in that pattern for a reason . Better Road Size Transtions . Saw in quite a few places that there were avenues and highthroughput roads in areas that didn ' t need them . Main arteries are usually the only roads that need to be massive , the rest of the networks often do fine if not better as smaller roads . Roundabouts . If your roundabout has traffic stopped inside of it , it is no longer functioning correctly . Yes , you have saved traffic from lights , but as soon as they become locked , roundabouts become far worse than lights could ever be . To fix this , limit the number of inputs into the circle , and don ' t zone anything on the roundabout itself , as traffic will come to a full stop and halt the entire flow whenever they park to interact with the location .
