Lack of Interstate Hwys In US Maps?

Hello, as you know the devs here make a beautiful game that has incredibly realistic physics. However, I'm a bit confused as to some design choices for the maps, specifically for the EC and WC USA maps. If you look at google maps, you will see a ton of blue shields which are the badges for interstate highways. You would expect to see them here in ECUSA and WCUSA, but no, you only get a few measly 2 lane roads that are US highways (For ECUSA of course). If WCUSA is based on LA or San Fransisco, You should see something like I-15, I-10, I-5, I-8, I-40 (Upper Area Only), I-80, I-680, I-880, I-580, Etc. and on ECUSA (Maine/NH/Vermont) there should be I-95, I-91, I-93, I-89, etc. So why isn't there one of those? (Sorry anybody who might've been offended by this)

 

Maybe they're gonna add it in the future, but yea it would be great to have those

 

The USA maps we have simply aren't large enough to really make use of a large interstate highway. West Coast is barely large enough to make use of the smaller highways it has. We'd need to have a map that's likely Italy sized or larger to realistically make use of a map like that.
