No application is really drawing nice ramps yet, but the smarts you can see in Google’s maps show that the data has the potential to support some nice visuals. Having played with doing this sort of thing in an application for work I can tell you that it’s no easy task. The data may be there, but it’s not straightforward. Someday I would imagine that the shapefiles for these highways will be in 3d and it’ll be possible to do a fully dimensioned render and style a 2d view appropriately. Then these things will really look nice. Well before then someone’s going to come out with something that looks really nice in all but the corner cases, though. The programmers working on this stuff are too clever not to.

basically, live maps and yahoo maps are incompetent. funnily, no mention of mapquest, but then their cartography always sucked particularly bad.
